IoT health monitoring system for preventing and controlling risk in confined space using microcontrollers

Abstract

Healthcare monitoring is a field that caught many researchers from the computer science community in the last decade. In the literature, various levels of people have been considered when proposing a health monitoring system. However, some aspects are still not adequately tackled such as monitoring workers’ health status within confined space where workers would be located in underground environment with less oxygen and a lot of dust. This paper proposes an IoT health monitor system for worker in confined places. The proposed system utilizes four types of microcontroller sensors including LM35 for measuring body temperature, heart beat rate sensor, blood pressure sensor and LPG gas sensor. All the aforementioned sensors are being connected via a GPS module in order to transmit the readings into a smartphone application. A simulation has been conducted to test the proposed sensors where competitive commercial measures have been used as a benchmark. Result of simulation showed that the sensors have fair accuracy that is near-identical to the benchmark.

Real-time monitoring system based on integration of internet of things and global system of mobile using Raspberry Pi

“…Blynk is a popular app, as shown by the fact that more than 100,000 people have downloaded it [25]. Blynk is a platform that allows iOS and Android applications to operate Raspberry, and a wide variety of other microcontrollers.…”

Door lock system based on internet of things and Bluetooth by using Raspberry Pi

“…In order to make the system work with multiple users the system should have database here google firebase is used because it has analytics, authentication, messaging, and real-time features that make it somewhat better than other databases and also the admin (house owner) should have an app to add/delete the users and open the door to visitor also the app should work on android and iOS and that can be done by using Expo [24], [25]. Expo is an open source framework for applications running natively on android, iOS, and the web [26]. Expo brings together the best of mobile and web, and enables features important to building and Scaling Apps, such as Live Updates, Real-Time App Sharing, and Web Support.…”
