MP503 MP-503 Air-Quality Gas Sensor For Occasions Such As Household Office Harmful Gas Detection
Detection Principle:
The MP503 gas sensor is for air quality detection. 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 a metal socket and cap. The conductivity of the sensor is affected by the concentration of the target gas. The higher the concentration is, the higher the conductivity of the sensor gets. Users can adopt a simple circuit to convert the variation of conductivity into an output signal corresponding to the gas concentration.
