Natural Gas Methane Sensor Module - MQ4

Product Description

This is the Natural Gas Methane Sensor Module - MQ4, which is highly recommended to integrate with Arduino.

Sensitive material MQ-4 gas sensor is used to clean the air in the lower conductivity of tin dioxide (SnO2). When there is the environment in which the combustible gas sensor , conductivity sensor with increasing concentration of combustible gases in air increases . Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-4 gas sensor is of high sensitivity for methane , propane , butane and has a strong sensitivity. This sensor can detect a variety of combustible gases, especially natural gas , is a low-cost sensor for a variety of applications .

Product Features

  • Size: 32X20X22mm/1.25*0.78*0.86”
  • The main chip: MQ-4 gas sensing probe
  • Operating voltage: DC 5V
  • Power (current) : 150mA
  • DO Output: 0.1V/5V
  • AO Output: 0.1-0.3V
  • Indication of the signal output
  • Dual signal output (analog output, and TTL level output)
  • TTL output signal is low. (When low output signal light, and can be connected directly to the microcontroller)
  • 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage.
  • Of methane gas, the natural gas has better sensitivity
  • Applications: Suitable for home or factory methane gas, natural gas, and other monitoring devices.
