About This Item

• This is a simple to use Gas Sensor Module which can sense the presence of combustible gases mainly Hydrogen, Methane, CO Smoke, and Propane in the air.
• The module uses our MQ-2 sensor.
• It simplifies interface to the odd pin spacing of the sensor and provides interface through 4 0.1" header pins. It provides both an analog output corresponding to the concentration of the gases in the air and an easy to use digital output.
• The onboard potentiometer can be used to set the maximum gas concentration beyond which the digital output gets triggered.
• Just power the module with 5V, set the threshold and you may get the output! 
• An onboard LED signals the presence of any gas. The digital output can be easily interfaced to an Arduino/ microcontrollers and other circuits.
• The analog output can be hooked up to an ADC of a microcontroler to get a wide range of sensor reading.
