In this IoT project, we will design an IoT ESP32 & PMS5003 Based PM2.5 & PM10 Monitoring System along with an Automatic Air Freshener System. The device can monitor and measure the PM2.5 & PM10 concentration in the air. It can also activate the air freshener when the PM Level exceeds the danger value. The device can be used in the house, industry, schools, office, and around crowded places.
Particulate Matter (PM) refers to microscopic particles of solid or liquid matter suspended in the air. PM is particulate matter, and 10 and 2.5 are diameter measurements: 10 micrometers or less, and 2.5 micrometers or less. Particulates are the most harmful form of air pollution. PM2.5 & PM10 has the ability to penetrate deep into the lungs, bloodstreams, and brain, causing health problems including heart attacks, respiratory disease, and premature death.
So, we have proposed an IoT Based System using ESP32 WiFi Module & PMS5003 Particulate Matter PM2.5 & PM10 Sensor. The device can be embedded on a small PCB. The device when powered on starts measuring the Particulate Matter Concentration in Air & displays the real-time value on a 0.96″ OLED Display. The ESP32 also connects to the WiFi Network and uploads the data to the Web Server. Using the Local IP address of ESP32, you can get the PM1.0, PM2.5 & PM10 value on any Web Browser. The Web Page doesn’t need any refreshing as the Ajax code is already implemented.
The Air Quality Index (AQI) value anything above 50 is unhealthy for breathing. So, when the pollution level exceeds in air, the fan turns on automatically to blow fresh air. Instead of Fan, you can use any other air freshening device like a humidifier connected to the relay.
