US Patent 11788999 Sensor device and gas monitoring system

A gas monitoring system includes at least one sensor device that detects gas and outputs a detection result; and a gateway that receives the detection result. The at least one sensor device includes a sensor module having a gas sensor that detects gas; an analog-to-digital (A/D) converter that processes the detection result outputted from the gas sensor; a communication module that communicates with the sensor module and transmits information processed by the A/D converter exteriorly of the at least one sensor device; a power source that is an electric power source of the sensor module; and a power source that is an electric power source of the communication module.
