DC24V GM 202B Portable Smoke Detector RL Adjustable MEMS Sensor
Portable Smoke Detector With MEMS Smoke Gas Sensor GM-202B
Features:
MEMS smoke gas sensor consists of a Si based micro-hot plate based on the MEMS process and a metal oxide semiconductor gas sensitive 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
Household smoke alarms, industrial smoke alarms and portable smoke detection devices
Adopt MEMS process, strong structure, high sensitivity to smoke and propane
Small size, low power consumption, high sensitivity, fast response recovery
The driving circuit is simple, stable and long life
