IOT BASED AIR QUALITY MONITORING SYSTEM
IOT BASED AIR QUALITY MONITORING SYSETEM USING ESP32,MQ135,DHT11 Air Quality is very important in Human life. In an era of growing industrialization ,urbanization and increased environmental health awareness is need to precisely quantify air contaminants has become critical .Poor air quality can have adverse effect on human health, ecosystem and the environment. Air Quality goes down when the enough amount of harmful gases present in air .In order to analyze an IOT based Air Quality Monitoring system is developed . REQUIRED COMPONENT: DHT 11 SENSOR MQ135 SENSOR ESP32 BLOCK DIAGRAM: CIRCUIT DIAGRAM AND EXPLANATION: The DATA Pin of DHT11 sensor is connected to D4 pin in ESP32 and the A0 pin of the MQ135 sensor is connected to D34 pin in ESP32 .The 3V3 and GND pin of ESP32 is connected to the VCC and GND...
