Catalytic combustion methane sensor module
Support UART and MODBUS-RS485
Catalytic combustion sensor
Outstanding anti-interference
Temperature compensation
Reliable service for sustainable cooperation
FS01200B is a catalytic combustion gas sensor that works based on the principle of catalytic combustion. When combustible gas comes into contact with the detection element, the resistance increases and the output voltage change is directly proportional to the gas concentration. The compensation element has a correction and compensation effect on changes in temperature and humidity. It uses a high-stability gas sensor and a high-performance microprocessor, and supports UART output and Modbus-RS485 output for convenience. The module adopts precise automated calibration and testing equipment, which reduces human interference and ensures accurate and consistent data in large-scale production.
