The hydrogen sensor is based on the principle of catalytic combustion to detect the concentration of hydrogen in the air. The front end of the sensor uses a chip prepared by the MEMS micro-hot plate process that meets the vehicle standard, and obtains a stable and reliable signal through temperature compensation and signal filtering and amplification. The sensor is supplied with high-performance wear-resistant cables, custom lengths, Dallas IDs and connectors.
