MQ 2 Gas Sensor The MQ 2 gas sensor is used to detect or monitor the concentration and/or presence of combustible gases in the air. It features a simple drive circuit, stable, long life, fast response, and a wide Due to its high sensitivity to hydrogen, LPG (liquid petroleum gas), methane,

6/5/2016· What is an MQ2 Smoke Sensor? The MQ2 smoke sensor is sensitive to smoke and to the following flammable gases: LPG; Butane; Propane; Methane; Alcohol; Hydrogen; The resistance of the sensor is different depending on the type of the gas. The smoke sensor has a builtin potentiometer that allows you to adjust the sensor sensitivity according to how accurate you want to detect gas.

29/9/2019· Description: This project is based on Gas leakage detection or smoke detection using the MQ2 gas/smoke sensor, Arduino Uno, and GSM sim900A module. This project is used for the Gas/Smoke detection, once the Gas/Smoke is detected a message is sent to the owner. This Project can be installed in kitchens, Rooms, etc.

16/2/2018· Features of the MQ sensors. Most sensors of the MQ series operate with working voltages that are typically at 5V, and have a lower absorption of 1 watt (5V here means less than 200 milliampere); such an absorption is mainly due to the heating element drawing power. As for some MQ sensors, the heater is powered at 2V: a low and atypical voltage ...
