Product Introduction
The The MMD1008T gas sensor module uses a metal oxide semiconductor sensor. When a trace amount of alkane gas reach sensor surface, the conductivity of the sensing material will increase. The change in conductivity related with gas concentration. Through the magnitude of the change in conductivity, the sensor can sense the degree of gas leakage in the air. For example, when indoor leaking gas molecules contact the sensor, the sensor can produce a conductivity change. Using this sensitive characteristic of the sensor, and then through a simple single-chip microcomputer and firmware control, the alarm device can be intelligently started, and the exhaust ventilation equipment can be started at the same time.
