Refrigerant Sensor
Planar semiconductor sensor for measuring freon
Application:
Refrigerant gas detection devices for home and environment, etc.Product characteristics:
This product has high sensitivity to refrigerant gasDescription
The MQ-5110 refrigerant gas sensor adopts a multi-layer thick film manufacturing process. A heater and a metal oxide semiconductor gas-sensitive layer are made on both sides of a micro Al2O3 ceramic substrate and packaged in a 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.
