Principle Introduction:
research and produce air quality monitoring gas sensor for home and office
air cleaners, and fresh air system.
MP135 gas sensor is for air quality. It adopts multilayer thick film
manufacturing technology. The heater and metal oxide semiconductor material
on the ceramic substrate of subminiature Al2O3 are fetched out by electrode
down-lead, encapsulated in metal socket and cap. Conductivity of the sensor
is affected by the concentration of target gas. The higher the concentration
is, the higher conductivity of sensor gets. Users can adopt simple circuit
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.
