Independent combustible gas detectors suitable for small catering establishmentsWorking Principle:
The detector is mainly composed of sensors, microcontrollers, operational amplification circuits, communication chips, etc. The sensor converts the gas concentration into an analog electrical signal, which is then amplified through operation, converted into a digital signal by a microcontroller, and finally converted into a digital signal through a communication chipM-BUS/4-20mA/RS485 standard signal, uploaded to the controller.
