“The aim of this project is to design and implement an air quality monitoring system. This project activates actuators to be able to maintain better air quality around us. This project can be used in our houses, warehouses, and greenhouses. It has a line following the robot on which there is the sensor that measures temperature, humidity, light intensity, and the presence of gas around. Whenever the parameters go beyond the set threshold, it activates an output to try to cancel out the change which is caused. Moreover, the data read is stored in a NodeMCU ESP8266, an IOT module, which is then transferred to the Blynk cloud app. All the data collected is accessible through the Blynk on a smartphone. The user can also see which actuator is in use.”
