Design of Electronic Blood Pressure Testing System

With the continuous development of electronic technology, the previous traditional methods of blood pressure testing are far from meeting people’s requirements. Fortunately, the advent of electronic blood pressure meters has shown great convenience and potential. Against the backdrop, a new electric blood pressure testing system based on a CC3200 LaunchPad is proposed in this paper, which uses a pressure sensor to collect the information of static pressure and fluctuation of blood pressure, and then transmits the processed data to the software in PC. The software in PC analyzes the data by oscillometric method and Gaussian fitting method, and then the static pressure, systolic pressure and diastolic pressure are calculated and displayed. Test results show that the blood pressure testing efficiency is greatly improved by this system with its high accuracy and reliability, which can meet the requirement of the AAMI (Association for the Advancement of Medical Instrumentation) standard.

IoT based real time water level monitoring using Texas instruments' CC3200

Objective: To monitor and control the water level in real time using IoT and cloud computing technologies to avoid the wastage of water in water storage tanks/sumps. Methods/Analysis: The level of water in a tank is detected by using ultrasonic sensor HC-SR04 which works on the principle similar to radar/sonar by converting electrical energy to acoustic waves and vice-versa and it is interfaced with CC3200 Launchpad, on-chip Wi-Fi microcontroller from Texas Instruments. Geotagging Technique is used to easily track the location of the water overflow. Findings: Ultrasonic sensor measures the distance and the microcontroller reads the data and uploads to the ThingSpeak cloud for real time monitoring and graphical representation. When the water reaches the reserve position and normally the motor will be switched off. Once the water attains a maximum level before overflow occurs. In case failure of the motor actuator (relay) it needs a physical switching of the motor. Such a scenario is tackled by sending an alert to the mobile using GSM SIM900A (Global System for Mobile communication Subscriber Identity Module) as such, failure of the actuator is taken care off. Novelty: In this study, we have designed an IoT based water level indicator with minimum power consumption which can be used for Domestic applications. Keywords: Water level, GeoTagging, IoT, CC3200, ThingSpeak cloud

Design and Formal Analysis of an Authentication Protocol, eWMDP on Wearable Devices

For wearable devices, this paper proposes an authentication protocol eWMDP. We formally model and analyze it. In the execution model of the protocol, a Dolev-Yao adversary is constituted. With the above, various security properties can be defined for measuring security performance. Our protocol can achieve the injective-auth property, in which case it surpasses another existing wearable authentication protocol—WMDP. In addition, our analysis work is confirmed by Scyther and tamain-prover, and the two protocols are implemented on PC and on Ti CC3200 LAUNCHPAD widely used in wearable devices in the meanwhile. The results of experiments highlight the higher transmission efficiency of eWMDP under various configurations, including different platforms, sorts of combinations of encryption algorithms and hash algorithms, and sending packets in different sizes.

Implementation of Cloud Connected Smart Robot for Environmental and Industrial Platform

<p>Cloud robotics is an emerging field that is centred on the benefits of converged infrastructure and shared services of a cloud computing environment. In this paper, a system is designed with an autonomous Pick and Place robot to sense environmental data such as temperature and Motion, along with GPS coordinates and sends them on the cloud. The mobile robot is controlled using an LPC1764 microcontroller and communicates with the cloud via a CC3200 Launchpad. A private cloud is set up using Open Stack that provides Infrastructure as a Service. The collected data are stored in a cloud server which could be viewed through a mobile app and can be used to create awareness about the environmental changes of the location under study. A proof-of-concept prototype has been developed to illustrate the effectiveness of the proposed system.</p>

Measurement and Monitoring of Soil Moisture using Cloud IoT and Android System

Objectives: Soil moisture information plays an important role in environmental monitoring, agricultural production and hydrological studies. Particularly, agricultural yield depends on several growing parameters like temperature, humidity, soil moisture and pH of the soil, etc. In this paper, we have designed and developed a system for measuring and monitoring soil moisture by interfacing low-cost soil moisture sensor with CC3200 LaunchPad and using Internet of Things (IoT), Cloud computing and Mobile computing technologies. Methods/Statistical Analysis: Two types of soils, namely red and black were collected from the field and experiments were carried out at room temperature. Moisture levels were measured using the commercially available soil moisture sensor: FC-28. Such values downloaded from the Cloud (earlier these values are uploaded into AT&T’s M2X Cloud technology and mobile application using CC3200 LaunchPad) are compared with the gravimetric dry basic technique. The results are in agreement with a deviation of 2%. Findings: Data corresponding to the moisture contents of red and black soils were uploaded to the AT&Ts’ M2X Cloud and accessed on-line and monitored the humidity levels on the screens of the mobile/laptop. In parallel the data acquired is also stored in the form of excel sheet for further processing. Conclusion: In this paper, we have designed and developed a Cloud computing Android system that gives on-line information about soil moisture. The results obtained for two types of soils are uploaded to the Cloud and accessed through the mobile/laptop from a remote area are presented.

Field Monitoring and Automation Using IOT in Agriculture Domain

Agriculture sector in India is diminishing day by day which affects the production capacity of ecosystem. There is an exigent need to solve the problem in the domain to restore vibrancy and put it back on higher growth. The paper proposes an e-Agriculture Application based on the framework consisting of KM-Knowledge base and Monitoring modules. To make profitable decisions, farmers need information throughout the entire farming cycle. The required information is scattered in various places which includes real time information such as market prices and current production level stats along with the available primary crop knowledge. A knowledge dataflow model is constructed connecting various scattered sources to the crop structures. The world around is getting automated replacing manual procedures with the advancement of technology, since it is energy efficient and engross minimal man power. The paper proposes the advantages of having ICT in Indian agricultural sector, which shows the path for rural farmers to replace some of the conventional techniques. Monitoring modules are demonstrated using various sensors for which the inputs are fed from Knowledge base. A prototype of the mechanism is carried out using TI CC3200 Launchpad interconnected sensors modules with other necessary electronic devices. A comparative study is made between the developed system and the existing systems. The system overcomes limitations of traditional agricultural procedures by utilizing water resource efficiently and also reducing labour cost.
