IoT-based Dual Technology Motion Detector

Home security has become a prime concern in recent years. As technology is emerging every second, abundant IoT-based smart surveillance systems have been developed and implemented with many modern features to keep the home safe. The proposed project is an extended approach to the existing home security system. The project aims to reduce false alarm rates of the existing home security system by using a Dual Technology motion sensor. Dual-technology sensors are sensors that combine two different types of technology. The dual-technology sensor uses both PIR and ultrasonic sensors, activating the trigger only when both sensors detect any motion of an object. The proposed setup effectively reduces false alarms caused by inanimate objects. The trigger caused by the Dual Technology sensor sends a message alert to the specified phone number through the Twilio Programmable Messaging API. Ultrasonic technology is sensitive to motion toward and away from the detector; passive infrared technology (PIR) is sensitive to motion across the field of view. The future implications of the project are great as it can also be used in the Automation of lighting in homes, offices, and libraries.

IoT Sensor-based sustainable smart home management for human needs through Micro Controller

Smart home technology is emerging rapidly as an exciting new paradigm. Appliances inside the home can be watched over, managed, and controlled by the consumer. Additionally, the gadgets are linked together via the internet, enabling the user to remotely control features like home lighting, air conditioner, and security systems providing sustainable approach. To aid the elderly and others with disabilities, this paper’s major goal is to teach consumers how to properly handle their household appliances. Thus, a smart home is being developed where the environmental conditions like air conditioner, television and lights adjust themselves with the person entering the room or even according to the weather conditions. Due to the complexity, in this paper an Microcontroller, LCD and other necessary materials in place of TV, AC and light are used to show that if a house consists of two or more people how the LCD will adjust itself and displays the standard required channel, likewise same LCD adjusts itself to the standard temperature required by the person and similarly adjusts itself according to the person entering into the room. Additionally, if it is raining outside the LCD will display a monsoon mood song, this is done using rain sensor. If these sensors are connected to the cloud, then the information related to the person entering the room is stored. This information can be accessed using your mobile.

At present, the use of indoor lighting fixtures in nursing homes is too monotonous and tedious, and their potential has not been effectively explored. By utilizing emotional design theory and fully considering the emotional needs of the elderly, an emotional design strategy for elderly care home lighting fixtures is constructed from four aspects: appearance design, functional design, and lighting atmosphere creation, thereby improving the quality of life and happiness of the elderly.

The spectral composition of a white light influences its attractiveness to Culex pipiens mosquitoes.

Insect attraction to artificial light can potentially facilitate disease transmission by increasing contact between humans and vectors. Previous research has identified specific wavelength bands, such as yellow and red, that are unattractive to biting flies. However, narrow-band, non-white lights are unsuitable for home lighting use as their very poor color rendering is often considered aesthetically undesirable. The creation of a white light that is unattractive to insects has so far remained elusive. White light can be created by combining a number of narrow-band light-emitting diodes (LEDs). Through choice chamber experiments on Culex pipiens (Cx.pipiens) mosquitoes, we examine whether combining specific wavelength bands has an additive, subtractive or synergistic effect on insect attraction. We show that a white light created by combining narrow-band red, green and blue (RGB) LEDs is less attractive to Cx.pipiens than a broad-spectrum white light; and that a white light created by combining narrow-band blue and yellow LEDs is more attractive than a broad-spectrum white light. White light produced by RGB combinations could therefore serve as a safer and cheaper light in countries where phototactic vectors and vector-borne disease are endemic.

Semiotic Approach in Lighting Product Design

Today, in addition to the basic functions of saving from darkness, it is also important for the lighting products to carry aesthetic values. In the designs, it is aimed to show the spaces different than they are, even to highlight them, to present successful, creative, artistic images and to create visual effects.
 Lighting products are design products that contain aesthetic elements in terms of being selectable and attracting attention. Industrial products carry meaning in respect to their cultural and communal reality. Therefore, these products are means of communication, and signs are one of the important tools for establishing this communication. In terms of designers, it is important to use the signs conveniently to convey the product to the target group.
 The aim of this study is to reveal how the semiotic approach can contribute to the design process. It is foreseen that the designs that are created by the designers with the inspiration of semiotic approach can easily find response in terms of marketability and perceptibility in the target audience. 
 In the study, as a method some home lighting products were selected from various sources and the examples were analyzed by using Peirce's triple semiotic classification of icon, index, and symbol. As a result of this semiotic analysis, it has been determined that using the visual elements in lighting product design is a frequently used method in design to make the products to be adopted by the target group. In the product design process, it has been seen that the semiotic elements guide the designers with deliberative placements, give them a creative perspective and inspire them.

Pemanfaatan Elektrolit Air Laut Sebagai Sumber Energi Listrik Baterai Dengan Elektroda Tembaga – Aluminium

Electrical energy demand is increasing from time to time. Most sources of electrical energy come from petroleum, natural gas, and coal. Even though this energy source is non-renewable, the amount is dwindling, and it produces carbon emissions that can cause the greenhouse effect. Indonesia is an agrarian country whose territory is more than seventy percent of the ocean. Natural resources: seawater and beach sand are certainly very abundant. In this study, this natural material is used by researchers as a source of electrical energy in the form of a battery. As far as researchers know, research on the manufacture of battery cells by direct use of natural resources does not yet exist. Much is preliminary research on the extraction of basic materials so almost all research on batteries costs a lot of money by methods that are not simple. Therefore, this research is very important, because it uses a simple assembly method which is certainly time-saving and cost-effective. The battery array made consists of [Cathode || Electrolyte + Microporous Separator || anode]. The seawater-salt water battery cells made successfully turn on the lights, both LED lamps, and home light bulbs, with a large current generated of 13.56mA. The voltage produced by a battery cell is 1.31 V, while the series voltage for 2-3 batteries is 2.55 V and 3.6 V, respectively.

Evening Light Intensity and Phase Delay of the Circadian Clock in Early Childhood.

Late sleep timing is prevalent in early childhood and a risk factor for poor behavioral and health outcomes. Sleep timing is influenced by the phase of the circadian clock, with later circadian timing linked to delayed sleep onset in young children. Light is the strongest zeitgeber of circadian timing and, in adults, evening light produces circadian phase delay in an intensity-dependent manner. The intensity-dependent circadian phase-shifting response to evening light in children, however, is currently unknown. In the present study, 33 healthy, good-sleeping children aged 3.0 to 4.9 years (M = 4.14 years, 39% male) completed a 10-day between-subjects protocol. Following 7 days of a stable sleep schedule, an in-home dim-light circadian assessment was performed. Children remained in dim-light across 3 days (55 h), with salivary melatonin collected in regular intervals throughout each evening. Phase-shifting effects of light exposure were determined via changes in the timing of the dim-light melatonin onset (DLMO) prior to (Day 8) and following (Day 10) a light exposure stimulus. On Day 9, children were exposed to a 1 h light stimulus in the hour before their habitual bedtime. Each child was randomly assigned to one intensity between 5 and 5000 lux (4.5-3276 melanopic EDI). Across light intensities, children showed significant circadian phase delays, with an average phase delay of 56.1 min (SD = 33.6 min), and large inter-individual variability. No relationship between light intensity and magnitude of the phase shift was observed. However, a greater percentage of melatonin suppression during the light exposure was associated with a greater phase delay (r = -0.73, p < 0.01). These findings demonstrate that some young children may be highly sensitive to light exposure in the hour before bedtime and suggest that the home lighting environment and its impact on circadian timing should be considered a possible contributor to behavioral sleep difficulties.

O024 Modifying light environments according to individual circadian light sensitivity

Abstract Introduction Large inter-individual differences exist in how sensitive the circadian system is to light. Circadian light sensitivity can be affected by medications, such as antidepressants, and varies as a function of age and some mood disorders. Using a computational model, we investigated how differences in an individual’s light sensitivity can be offset by changes in their light environment to maintain stable circadian timing. Methods A previously validated computational model was used to simulate sleep and circadian timing under realistic assumptions about light and sleep schedules in day workers across two weeks. The model predicted circadian phase (dim light melatonin onset) and sleep onset/offset times for each day. Simulations were repeated varying two parameters: (i) light sensitivity, representing changes in the dose-response curve to light, and (ii) evening illuminance, representing home lighting levels after sunset. Results Higher light sensitivity and higher evening illuminance levels resulted in systematically later predicted sleep and circadian timing. The effects of increasing light sensitivity could be offset by reducing the level of evening illuminance, with this relationship holding over a wide range of light sensitivity values. Low light sensitivity combined with high evening illuminance produced a non-entrained (non-24) phenotype; decreasing evening illuminance from this state resulted in stable entrainment. Discussion We are only beginning to understand the influence of medications and health conditions on circadian light sensitivity. Our results show how modifications to evening light levels can be used to offset impacts of variable light sensitivity on sleep and circadian timing.

Evaluating an integrative lighting design for elderly homes – a mixed methods approach

The experience of light in a space and the physiological effect of light combined is complex to study. Methods which combine parameters from the fields of the biological, visual and atmospheric effects of light through a combination of both qualitative and quantitative data collection on site, seem more important than ever to validate the potentials of integrative lighting. A case study, conducted in two elderly homes in Copenhagen and Aarhus, in Denmark, is used to evaluate a mixed methods approach, assessing an integrative lighting design solution. Luminaires with circadian settings are implemented as a supplementary lighting with the aim of supporting various objectives, including biological stimulation and a homely atmosphere in the elderly homes. To evaluate the implementation of the lighting, a convergent mixed methods approach is used, collecting quantitative and qualitative data. In parallel to collecting quantitative measurements, such as melanopic equivalent daylight illuminance (mEDI) and photopic lux, semi-structured interviews based on questionnaires and card-sorting, on the same subjects, are carried out. To evaluate the approach for evaluating the implementation of this integrative lighting design, three criteria are introduced: a) integration, b) flexibility and c) validity. The integration of results enabled to compare the different methods and findings to identify and study correlations, differences or contradictions. That was conducted across the three topics: biological, visual, and atmospheric effects of the integrative lighting design solution. A framework for a holistic approach for evaluating lighting in elderly homes was defined, with an indication of the need for further development in an iterative process.

Pengembangan Model Pembangkit Listrik Tenaga Picohydro Tipe Turbin Cross Flow Head Rendah

The provision of food, energy supply, and the provision of information are The food provision, energy supply, and information delivery are controlled to improve people's welfare. In 2011, the national electricity production by PLN was 11% new and renewable energy. 6% hydropower and 5% geothermal. PLN plans the geothermal to be 13% and hydropower to be 6%. The availability of independent PhPP has been built by many communities. PhPP with a waterwheel drive provides a capacity of about 100 watts thus it is only enough for home lighting, whereas the hydro energy potential of the area is quite abundant. The development that has been carried out has several weaknesses; PhPP plump turbine type requires a high head which becomes a constraint for agricultural irrigation, in the other hand PhPP waterwheel type has low efficiency. The research was conducted to develop PhPP low head cross-flow turbine type, which is more efficient. The development begins with the experiment of the PhPP cross-flow turbine model to optimize the ratio of the diameter and width of the runner. A preliminary case study provides experimental results for a cross-flow turbine's torque and power parameters at a flow rate of 0.053 m3/s. Changes in the turbine diameter and width ratio are optimum at a runner width of 10 cm.

Tunable White Light for Elders (TWLITE): A Protocol Demonstrating Feasibility and Acceptability for Deployment, Remote Data Collection, and Analysis of a Home-Based Lighting Intervention in Older Adults.

Sleep disturbances are common in older adults and may contribute to disease progression in certain populations (e.g., Alzheimer’s disease). Light therapy is a simple and cost-effective intervention to improve sleep. Primary barriers to light therapy are: (1) poor acceptability of the use of devices, and (2) inflexibility of current devices to deliver beyond a fixed light spectrum and throughout the entirety of the day. However, dynamic, tunable lighting integrated into the native home lighting system can potentially overcome these limitations. Herein, we describe our protocol to implement a whole-home tunable lighting system installed throughout the homes of healthy older adults already enrolled in an existing study with embedded home assessment platforms (Oregon Center for Aging & Technology—ORCATECH). Within ORCATECH, continuous data on room location, activity, sleep, and general health parameters are collected at a minute-to-minute resolution over years of participation. This single-arm longitudinal protocol collected participants’ light usage in addition to ORCATECH outcome measures over a several month period before and after light installation. The protocol was implemented with four subjects living in three ORCATECH homes. Technical/usability challenges and feasibility/acceptability outcomes were explored. The successful implementation of our protocol supports the feasibility of implementing and integrating tunable whole-home lighting systems into an automated home-based assessment platform for continuous data collection of outcome variables, including long-term sleep measures. Challenges and iterative approaches are discussed. This protocol will inform the implementation of future clinical intervention trials using light therapy in patients at risk for developing Alzheimer’s disease and related conditions.
