Product Description:
GM-502B GM502B MEMS Air Quality VOC Sensor Is Used For Indoor Air Quality Monitoring Such As Smoke Alarms
Features:
MEMS VOC gas sensor is composed of a MEMS process SI-based micro-hot plate and a metal oxide semiconductor material with low conductivity in clean air. When the detected gas is present in the ambient air, the conductivity of the sensor changes. The higher the concentration of this gas, the higher the conductivity of the sensor. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the concentration of that gas.
Product advantage
GM-502B air quality VOC sensor adopts MEMS technology, strong structure and good shock resistance; It has the characteristics of small size, low power consumption, high sensitivity, quick response recovery, simple drive circuit, good stability and long life
Main application
GM-502B Air quality VOC sensor is suitable for indoor air quality monitoring, mobile phones, computers and other consumer products, air quality detection is also suitable for exhaled air physical detector, indoor smoke alarm and so on.
