Basic Information

Detailed Description	The MEMS smoke gas sensor consists of a Si-based micro-hotplate based on MEMS technology and a metal-oxide-semiconductor gas-sensitive material with low conductivity in clean air. When the detected gas is present in the ambient air, the sensor's conductivity changes; the higher the concentration of the gas, the higher the sensor's conductivity. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the gas concentration.
Main Applications	Home smoke detectors, industrial smoke detectors, and portable smoke detection instruments.
