Duct temperature and humidity sensor

Duct temperature and humidity sensors require regular mainte-nance to maintain product performance, and there has been a demand to reduce the number of maintenance tasks.
To respond to this demand, we developed a compact humidity element, and modularized the sensor so that the temperature and humidity sensing parts can be swapped out. To compensate for a lower S/N ratio due to miniaturization of the humidity element, we digitalized the measurement signal processing, which also allowed us to resolve issues and make improvements in product design and production management.
