MP801 Air-Quality Gas Sensor

Principle Introduction:
 MP801 gas sensor is for air quality,It adopts multilayer thick film manufacturing technolgy. The heater and metal oxide semiconductor material on the ceramic substrate of subminiature Al2O3 are fetched out by electrode down-lead, encapsulated in metalsocket and cap. Conductivity of the sensor is affected by theconcentration of target gas. The higher the concentration is, the higher conductivity of sensor gets. Users can adopt simple circuit to convert to convert variation of conductivity into output signal corresponding to gas concentration.

Applications :
 It is used in occasions such as household and office for harmful gas detection,automatic exhaust device,air cleaner & etc.

Technical parameters :

Tips:For more parameter information, please refer to the latest manual provided by salesman.
