Neonatal Health Monitoring System with IOT Application

The body temperature and heart rate are important parameters to monitor the neonatal situation. Neonatal need to be monitored closely in Neonatal Intensive Care Unit (NICU) to allow quick actions by physicians when any problems occur. The lack of systems that able to alert and indicates any warning condition of neonatal in NICU is one of the problems faced by most of the hospital. To reduce the complexity of the system at the NICU for monitoring the Neonatal condition from time to time, the health monitoring system using the Android app has been introduced. This system was introduced to improve the existing system to give alert and warning sign so that early precautions can be done. The project involves the LM35 temperature sensor and pulse sensor which is controlled by the Arduino Uno microcontroller with the help of instructions C / C ++, and Bluetooth networking system. This allows the user to monitor the baby’s condition through applications that use Bluetooth networking system. Users must have the application that can be downloaded on Google Play. Furthermore, this system is not only applicable for the physicians but also for others to monitor the condition of Neonatal even though they are outside of the NICU. The neonatal condition can be checked by the LCD display.

DESIGN OF METAL HEAT CONDUCTIVITY MEASUREMENT USING PROBE METHOD

This study aims to design a tool that can measure the heat conductivity of metals by the Probe method. The design method was used by using a heat-flowed metal beam and the use of an LM35 temperature sensor to measure temperature changes on the probe. We are designing a measurement system based on conduction heat transfer. The metal used in the design is aluminum and carbon steel. For each metal tested, an LM35 temperature sensor is placed on the metal to find out that a temperature change has occurred. The conductivity value can be obtained from the temperature difference between the probe and the metal being tested, the temperature change of the probe, the temperature change of the metal being tested, and the heating time. This value is processed and calculated by the microcontroller into the value of heat conductivity. The measurement results show that the average heat conductivity value is 214.93 W/moC for aluminum and 53.81 W/moC for carbon steel.

Development of a System to Control Flow of Coolant in Turning Operation

Automation of cooling system in machine tools is an effective method for achieving higher productivity and increased tool life. A cooling system is designed to control the operating temperature on the cutting tool tip by circulating coolant through a reservoir built on the top of the machine tool. This arrangement maintains the coolant flow rate as per variation of cutting tool tip temperature sensed by LM-35 temperature sensor which is located 1 cm away (calibrated distance) from the cutting tool tip and whose output voltage is linearly proportional to the temperature. Coolant flow rate is varied in such a manner that the temperature of the cutting tool tip remains within fixed value of temperature. The aim of present work is to develop a cooling control panel system to provide coolant on cutting tool tip in turning operation of mild steel. The coolant flow rate can be increased or decreased as per the variation of sensor temperature during turning of mild steel with high speed steel (HSS) cutting tool at different depth of cut, and spindle speed ,keeping feed rate constant which results in effective cooling of the cutting tool tip. The experiments were carried out with and without use of coolant. It supplies the coolant as per instructions of cooling control panel system which results in saving of coolant as well as power. The mechatronics application of designed cooling control panel system enabled the reduction in cutting tool tip temperature in more robust way as compare to conventional cooling system.

Low-Cost Elderly Healthcare Monitoring System

One of the most common problems we face today is the lack of a proper home-based health care system for the elderly. In the Philippines, there are several elderly people living alone in their homes, with no one to look after them. This is a problem because it’s going to be difficult for them to ask for help if they ever get into an accident. Some systems are already available to monitor a person, but they are limited to only one or two parameters, namely the pulse rate and the temperature. In this study, a low-cost elderly health monitoring system was designed and developed using Arduino Uno, ADXL345 (Accelerometer), LM35 (Temperature Sensor), Pulse sensor and GSM module. This system includes pulse rate monitoring, temperature monitoring and fall detection with the addition of an SMS notification system that will notify the contact person if there is an accident or if the patient’s vital signs are below normal. The initial results showed that the system was able to accurately measure the temperature, the pulse rate, detect falls and to notify the registered number via SMS.

Smart Wearable Health Device for Heart Rate and Temperature Measurements

Lack of communication can be seen in many aspects, such as public health, and recycling. We found that in public health people suffer from lack of facilities and it may lead to death, but building new hospitals is not the right solution, but improved communication is. To solve both problems with a simple solution, the Internet of Things (IoT) had to be involved. So, we proposed a solution, which is a WHD (wearable health device) that measures temperature and heart rate for the patient and compares them to a database, it consists of Arduino Nano wired to both LM35 temperature sensor and pulse sensor. The readings are displayed on an OLED screen, as well as on a mobile application called ThingView. If the readings are abnormal, an action would be taken either to contact a relative or the ambulance, depending on its severity. It would decrease the trips to hospitals. We have tested for the device's efficiency and sensor calibration, and the results were promising. The competence of the pulse sensor is very high as its relative error is ±0.07. The temperature sensor (LM35) has very low relative error which is ±0.00356. The final cost was computed to be $26.5.

Fire disaster early detection system in residential areas

The number of residential fires in urban areas is increasing every year. The use of automatic fire detection technology can prevent greater fire disaster losses. The fire detection system works by detecting increasing degrees of heat, ultraviolet radiation by flames, and gas leaks. The system will start automation if the LM35 Temperature sensor, MQ2 Gas sensor, and Light Dependent Resistor (LDR) detect the occurrence of fire according to the initial settings on Arduino Uno. After Arduino Uno processes input data from the sensor, there will be a notification marked with the Buzzer and a text will appear on the Liquid Crystal Display (LCD) that describes the condition of the sensor reading. Arduino Uno configures data via the GSM SIM900A Module. The last process is sending short messages (SMS) from the GSM SIM900A Module to the receiver to notify the initial warning of a fire. the delay time in testing the farthest distance (100 cm) is as follows: LM35 140 second Temperature Sensor, 130 second MQ2 Gas Sensor and LDR 145 seconds.

The NI myDAQ component consists of input and output ports. To sense the temperature is necessary at a many places for example kitchen, refrigerators, air conditioners, storage rooms etc. At these spaces to sense the temperature and its appropriate hint is required since it can basis serious complications otherwise. For example, if the temperature in the food room room is greater than an accustomed threshold, it will be damaging for all of the food objects. We can similarly consider “Fire Alarm” which is an example of temperature sensor. This paper offers the evidence about how to use the Labview for LM35 temperature sensor using NI myDAQ.

The ascent of temperature on the planet can be caused because of a few elements like an unnatural weather change, ozone harming substance discharge and numerous other such factors. Climate change is one of the most discussed logical issues of the previous 20 years. The worldwide temperature of the earth has expanded on a normal of about 0.8 degree Celsius (1.4 degree Fahrenheit) since 1880. Since the control of this rising temperature is not in our hands, we have built a project that helps us control the speed of the fan in a room depending on the rise and fall of the room temperature. This paper discusses temperature based fan control fan speed control and monitoring the system using an Arduino system. The system uses an Arduino board to implement a control system. The study was conducted with the design and manufacture of automatic fan control system. Along with Arduino, we have use a temperature sensor LM35 to sense the temperature of the room. The fan control system discussed in this paper is economical, efficient and very reliable.

The Intensive Care Unit (ICU) ward situation tend to be very intense since the patients who are placed in the wards are usually critical condition patients. These patients need an intensive care by the nurses and physician since their condition are not very stable. Therefore, the nurses and physicians need to monitor them very frequent. So, the idea of this monitoring system is mainly to ease the nurses work by reducing monitoring frequency. This monitoring system also purposely built to make them alert about their patient thus, can minimize the risk of patients who are monitored. This monitoring system is using the microcontroller (Arduino Uno) which is connected to the laptop via Bluetooth to transfer the data of heart rate and body temperature of the respondent. This data was sense through Heart-Rate Grove sensor and LM35 temperature sensor. The data were processed and displayed on the laptop for every minute continuously. Different colour of LED was used as an indicator to notify the condition of the respondent’s pulse or body temperature either it was in high or low condition as a warning. For young adult with fever respondent, it shows the result of 81 bpm of heart rate and 37.63°C of body temperature with 3.83% and 0.65% of the Mean Absolute Percent Error (MAPE) respectively. This monitoring system has successfully built and able to display the data of the heart rate and body temperature of the respondent for every minute and able to facilitate autonomous monitoring tasks in the future.

Remote monitoring of BLDC motor using LabVIEW and zigbee

Brushless DC motors (BLDC) are preferred over brushed motors in industries because of many advantages such as increased reliability, reduced noise, higher speed range, better speed-torque characteristics, higher efficiency and high torque to weight ratio. This paper focuses on the remote monitoring of parameters of BLDC motor such as Temperature, Voltage, Current and Speed using Zigbee wireless technology and virtual instrumentation tool, LabVIEW.

Design, Construction and Testing of a Kerosene Powered Multi Bird-Egg Incubator

The demand for poultry products such as eggs, meat and birds is on the increase daily that the world can no longer depend solely on the natural mode of incubation hence, the need for artificial incubators. But not all countries have stable electricity supply; therefore, there is a need to fabricate other types of incubators that will not be powered by electricity. Hence the choice of kerosene powered incubator. Heat generated by the combustion of kerosene was transferred into the incubator chamber by conduction and circulated by means of a 12 V D.C fan powered by a 12volt battery device. LM35 temperature sensor was used as the temperature sensing device. Both the turning of eggs and heat generated from heat source were controlled by mechanically incorporated driver motors. The LM35 temperature sensor and the two stepper motors were controlled by a PIC16F877 microcontroller. Insulation of the incubator chamber was achieved by lining the inner portion of the incubator with fiber materials. The incubator was designed and constructed using locally available material to reduce cost with little or no dependence on electricity and more user friendly. The incubator was tested with 90 eggs each for the three birds (i.e Chicken, Quail and Turkey). The result obtained shows that quail has the highest hatchability of 93% followed by Chicken with 84.4% and lastly turkey with 70%. The unit cost for the incubator is ₦95,000.00. The above average efficiencies implied that the Incubator performed efficiently and effectively. The birds also look healthy and strong several days after they were hatched.

Guava is a fruit plant with various benefits for humans. Both the leaves and the fruit can be used to treat various diseases. As an example of the fruit to treat Dengue Hemorrhagic Fever, Tyfus, and so forth. The leaves can be used as traditional medicine to treat cough and diarrhea.&#x0D; In the highlands it is indeed cold and there is little possibility of plantation fires. However, fires can occur as a result of human activity both intentional and unintentional. The location of the plantation land that is relatively far from the residential population makes fires sometimes known too late. Therefore, it is necessary to create a tool to monitor the temperature and concentration of guava plantation smoke from a distance every day so that if the temperature or the density of smoke reaches a certain number that indicates the occurrence of fire then the tool will immediately send a notification via SMS to the plantation owner. In addition, the tool will immediately pour water from the reservoir or water reservoir into the guava plantation. In the water reservoir there is a tool to detect the volume of water. The device to be created uses the LM35 temperature sensor, MQ-2 smoke sensor, HC-SR04 Ultrasonic sensor, Relay, Arduino Uno R3 microcontroller and GPRS Shield along with the GSMSIM Card.
