Product details
product details
The WSP1110 semiconductor nitrogen dioxide sensitive element adopts advanced planar production technology to form a heater and metal oxide semiconductor gas sensing material on a micro Al2O3 ceramic substrate, which is led out by electrode leads and packaged in a metal socket and cap. When there is a detected gas present, the higher the concentration of the gas in the air, the higher the conductivity of the sensor. This change in conductivity can be converted into an output signal corresponding to gas concentration using a simple circuit
Sensor characteristics
This product has high sensitivity to nitrogen dioxide, with advantages such as fast response recovery, low power consumption, simple detection circuit, good stability, and long lifespan.
Main applications
Used for monitoring nitrogen dioxide emissions from urban automobile exhaust and industrial fuel combustion.
