Combustible Gas Sensor
Application:
It can be use for combustible gas leakage monitoring device, fire prevention / safety detection system for home, factory and commercialProduct characteristics:
long lifeDescription
The MQ-D5B combustible gas sensor adopts a multi-layer thick film manufacturing process to make a heater and metal oxide semiconductor gas sensitive layer on both sides of the micro Al2O3 ceramic substrate, packaged in the metal shell. The sensor conductivity changes in the presence of a detected gas in the ambient air. The higher the concentration of the gas, the higher the conductivity of the sensor
