Low Cost IoT Based Emission Monitoring System for Thermal Power Plants

Abstract

Nowadays, Internet of Things (IoT)) has turn out to be a part of an Embedded system for controlling and monitoring purposes. Monitoring of gases produced by thermal power plants is very much essential to mitigate their impact on the environment like air pollution also, to prevent health hazards to human beings. In this paper, an attempt is made to design IoT based Embedded application, a prototype, which is specifically developed for monitoring toxic gases released by thermal power plants. This system measures the concentration levels of Carbon Monoxide (CO), Particulate Matter (PM) released by thermal power plants. Various sensors are used to measure the concentration levels of the gases. Node MCU is used, to read data from the sensors and send it to the cloud using ESP8266 module. The data can be monitored by the environmental agency, either by using web application (Thingspeak) or mobile application (Blynk app). If the measured data is greater than the emission standards, an email notification is send to the Power Plant agency and they may initiate to limit the toxic emissions.
