Air Pollution Sensor MP503 TOVC Air Quality Detection Odour Pollution Fresh Air System
Product description
The MP503 air quality gas sensor uses a multi-layer thick film manufacturing process. A heater and a metal oxide semiconductor gas-sensitive layer are fabricated on both sides of a miniature Al2O3 ceramic substrate, respectively, and packaged in a metal casing. When the detected gas is present 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 change in conductivity into an output signal corresponding to the gas concentration.
Sensor characteristics
This product has high sensitivity to alcohol, smoke, isobutane and formaldehyde; it has the advantages of fast response recovery, low power consumption, simple detection circuit, good stability, long life and so on.
Application
For home environment and office harmful gas detection, automatic exhaust device, air freshener, etc.
