In this project, we are going to make an IoT Based Air Pollution/Quality Monitoring System with ESP8266, PM2.5 Particulate Matter Sensor, MQ-135 Air Quality Sensor & BME280 Barometric Pressure Sensor. We will monitor the Air Quality on Thinspeak Server using the internet.
This is a simple prototype for an Environmental IoT Air Pollution/Quality Monitoring System for monitoring the concentrations of major air pollutant gases. The system uses 3 sensors like PMS5003 PM2.5 Particulate Matter Sensor, MQ-135 Air Quality Sensor, BME280 Barometric Pressure Sensor. In this IoT project, you can monitor the pollution level from anywhere using your computer or mobile.
PMS5003 PM2.5 Particulate matter sensor from Plantpower measure particle concentration in PM1.0, PM2.5 & PM10. This MQ-135 Air Quality Sensor measures concentrations of gases such as CO, CO2, SO2, and NO2 and gives the result in PPM (Part per Million). Similarly, BME280 Measures environmental Temperature, Pressure & Humidity.
The sensors will gather the data of various environmental parameters and send them to the Thingspeak server which displays the data online after the interval of every 15 seconds. We can install this system anywhere and can also trigger some devices when pollution goes beyond some level like we can switch on the Exhaust fan.
