      Features:

      MQ-4 gas sensor-sensitive material used in clean air conductivity is lower in tin dioxide (SnO2). When the sensor is present in the environment in which the combustible gas, the sensor’s conductivity increases with the concentration of combustible gases in the air increases. Using a simple circuit can be converted to the change in conductivity of the gas concentration with the corresponding output signal. MQ-4 methane gas sensor for high sensitivity, propane, butane, and has a good sensitivity. The sensor can detect a variety of flammable gases, especially natural gas, and is a low-cost sensor for a variety of applications.

      Specifications: 

      Model: MQ-4
      1. Using high-quality dual-panel design, with power indicator and TTL signal output instructions;
      2. with a DO switch signal (TTL) output and AO analog signal output;
      3. TTL output valid signal is low. (When the output low signal light can be directly connected microcontroller or relay module)
      4. The analog output voltage, the higher the concentration the higher the voltage.
      5. Methane and natural gas have better detection sensitivity.
      6. there are four screw holes for easy positioning;
      7. Product Dimensions: 32 (L) * 20 (W) * 22 (H)
      8. With a long service life and reliable stability
      9. Rapid response and recovery characteristics
