Low Cost IoT Based Emission Monitoring System for Thermal Power Plants

Abstract
        Nowadays , Internet of Things(IoT) is the most growing technology. This can be used in embedded systems for monitoring and observing the atmospheric conditions. In this project , we have used IoT for monitoring the unwanted and toxic gases in the thermal power plants , which will leads to air pollution and hazards to health of the human lives. This system specifically developed for measuring the concentration levels of the Corbon monoxide(CO), Particulate Matter (PM) released by the thermal power plants. If the concentration levels of the CO and PM exceeds the particular threshold value, it will sends the notification to the Power plant agency using NodeMCU. Thingspeak Cloud and Blynk app used to monitor the status of the concentration levels of gases.

Proposed system
    Air pollution is the major problem nowadays. This will cause major health issues to the human lives, So , here We are using MQ – 7 sensor to monitor the concentration levels of the Corbon Monoxide and  PM2.5 dust sensor to monitor the level of Particulate Matter, NodeMcu used as the main controller to monitor the data’s from the sensors. If the sensor value exceeds the particular value it will send the alert notifications to the Power plant agency using IFTTT(IF This ,Then That). Thingspeak or Blynk app used to monitor the data’s.
