GM 502B MEMS VOC Sensor For Indoor Gas Air Quality Monitoring
MEMS VOC Gas Sensor GM-502B For Indoor Air Quality Monitoring
Features:
MEMS VOC gas sensor is composed of a MEMS process based on a Si microhot plate and a metal oxide semiconductor material with low conductivity in clean air. When the detected gas exists 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 is used to convert the change in conductivity into an output signal corresponding to the concentration of the gas.
Main application
Indoor air quality monitoring, mobile phones, computers and other consumer electronic products used to detect air quality, exhaled gas detector, indoor smoke alarm, etc
Adopt MEMS process, strong structure, good shock resistance
With small size, low power consumption, high sensitivity, fast response recovery
The driving circuit is simple, stable and long life
Specifications:
| Product type | MEMS VOC gas sensor | 
| Standard package | ceramic package | 
| Detection gas | ethanol, formaldehyde, toluene, etc | 
| Detection concentration | 1ppm ~ 500ppm |
