AI Technical Summary

Technical Problem

Sensors that sense oxygen and hydrogen are susceptible to contamination and deterioration of sensing function due to exposure to moisture and gases in the atmosphere, leading to a decrease in performance or failure of the sensor's circuitry.

Method used

An electrochemical apparatus is designed with a housing, a first member, and a second member between the housing and the first member, featuring through-holes and openings that control the entry and exit of water vapor to suppress contamination, using a dehumidifier and a duty cycle signal to reduce power consumption while maintaining sensing function.

Benefits of technology

The design effectively reduces the entry of water vapor, preserving the sensing function and preventing sensor failure, enabling accurate detection of oxygen and hydrogen with reduced power consumption.
