This tutorial walks you through building a smoke detector that not only senses smoke and other harmful gases in the air but also reads and displays smoke levels in PPM (parts per million). Here is the details from the seller: Features:. The MQ135 gas sensor is an air quality sensor for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke and CO2. The sensor requires two voltage inputs: heater voltage (V H) and circuit voltage(V C). LM35 Arduino Simulation in Proteus ISIS.The heart of the project is its microcontroller.In, an IoT based air pollution monitoring system was designed in conjunction with a web server that triggered an alarm whenever the air quality drops below the threshold. Air Sensor Arduino based air quality sensor Sensors used: DHT22 - temperature and humidity sensor MQ-2 - gas leakage detector.Open Arduino IDE and click to the Sketch tab. You can choose your favourite arduino board for this project. Arduino library for the MQ135 gas sensor. Mongoose OS api for MQ135 Air Quality sensor (CO2 meter) Based on ViliusKraujutis MQ135 library for Arduino. Code samples in the reference are released into the public domain.Mq135 library for arduino The internal resistance of this sensor changes as the density of the.
