Both B pins need to be connected to the analog input (A0). The right H pin needs to be connected to the ground (GND). A load resistor from 2kOhm to 47kOhm needs to be ...

information about the MQ2 sensor please refer to the datasheet. 7 How to use There''re two steps you need to do before getting the concentration of gas. First, connect the module with Grove Shield using A0 like the picture above. And put the sensor in a clear air and use the program below.

The Grove Gas Sensor (MQ2) module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by potentiometer.

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.

MQ2: Sensor Type: Semiconductor: Standard Encapsulation: Bakelite, Metal cap: Target Gas: Flammable gas, smoke gas sensor: Detection range: 300～10000ppm(flammable gas) Standard Circuit Conditions: Loop Voltage: Vc: ≤24V DC: Heater Voltage: VH: ± AC or DC: Load Resistance: RL: Adjustable: Sensor character under standard test conditions: Heater Resistance: RH

MQ2 gas sensor is an electronic sensor used for sensing the concentration of gases in the air such as LPG, propane, methane, hydrogen, alcohol, smoke and carbon monoxide. MQ2 gas sensor is also known as chemiresistor. It contains a sensing material whose resistance changes when it comes in contact with the gas.

The Grove Gas Sensor(MQ2) module is useful for gas leakage detecting(in home and industry). It can detect H2, LPG, CH4, CO, Alcohol, Smoke, Propane. Based on its fast response time.
