ACROBOTIC MQ-4 Methane and Natural Gas CNG Analog Sensor Breakout Board for Arduino Raspberry Pi ESP8266 MQ4 I2C 3~5VDC

This breakout board provides a convenient way to start using the popular MQ-4, a Methane and Compressed Natural Gas (CNG) Sensor Module. The MQ-4 detects the concentrations of Methane (CH4) gas in the air and outputs a corresponding analog voltage. The MQ-4 has high sensitivity to methane, as well as anti-interference to alcohol and other gases. It can be used in detecting equipments for gas leakages inside the home or industry. Although the sensor works great, please use certified equipment for reliable detection of gas leakages. Our design includes a protection resistor, as well as an adjustable one for tuning the sensitivity. The resistance of the sensitive component inside the MQ-4 varies as the concentration of the target gas changes. It features fast response, high sensitivity, and a wide range of detection. It can measure concentrations of Methane (CH4) of 300 to 10,000ppm. This breakout board makes it easy to connect this sensor to your microcontroller board or single-board computer such as Arduino, ESP8266, BeagleBone or Raspberry Pi! Features: Power Supply: 5VDC This breakout PCB facilitates using the MQ-4 sensor, specially on solderless breadboards! Sturdy (1.6mm), blue PCB with a 4-pin header on on side (VCC, GND, A0, and D0) 4-Pin header included (no soldering needed!) We have written useful guides for getting you started with the MQ-4: ESP8266: http://learn.acrobotic.com/tutorials/
