<b id="ijyu3"></b> <b id="ijyu3"></b> The sensor adopts a heated-semiconductor gas transducer whose surface resistance varies with the concentration of the gas detected.
The processor collects the sensor output voltage in real time and compares it with the threshold of alarm.
When the collection value is greater than the set value, the detector alarms, the alarm indicator turns on with alarm voice prompts, and outputs high level signals to control the valve action.
