Overview of this MQ2 Flammable Gas and Smoke Sensor
Introducing the Roboway MQ2 Flammable Gas and Smoke Sensor Module at the best price in India with Roboway. This sensor detects flammable gases like LPG, methane, propane, hydrogen, and smoke in the air. It works on 5V power supply and making it compatible with Arduino and other microcontrollers.
This sensor module gives both analog and digital outputs there is analog for measuring gas concentration and digital for set threshold alerts. It can be adjusted using the built-in potentiometer to match different environments. This sensor Comes pre-mounted on a breakout board with standard pin headers for easy wiring.
