MP-135 / MP503 Air Quality Monitoring Sensor Module – PM2.5, CO2, VOC, Temp & Humidity

Description

MP135 air quality/MP503 gas sensorFeatures: 
1. Good sensitivity to methane 
2. Wide concentration range
3. Strong anti-interference ability
4. Low power consumption
5. Fast responses recovery
6. Good stability
7. Long life
8. Low cost
9. Simple drive circuit Description: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.
