MQ-D4B Combustible Gas Sensor

Product Description:

MQ-D4B combustible gas sensor adopts multi-layer thick film manufacturing process, and makes heater and metal oxide semiconductor gas sensitive layer on both sides of micro Al2O3 ceramic substrate, which is encapsulated in metal shell. When the detected gas exists in the ambient air, the conductivity of the sensor changes. The higher the concentration of the gas, the higher the conductivity of the sensor. A simple circuit can be used to convert this conductivity change into an output signal corresponding to the gas concentration.

MQ-D4B combustible gas sensor main applications:

1. Combustible gas leak monitoring device for home, factory and commercial use, fire prevention/safety detection system.

2. Combustible gas leak alarm, gas leak detector.

MQ-D4B combustible gas sensor features:

MQ-D4B combustible gas sensor has good sensitivity to methane in a wide concentration range, and has the advantages of strong anti-interference ability, low power consumption, fast response recovery, good stability, long life, low cost, simple driving circuit, etc.
