Capacitive digital temperature and humidity sensor

The HSHCAL101B PC board module from Alps Electric is a capacitive digital temperature and humidity sensor for major home appliances.

As well as being easy to install in a position enabling accurate measurement of temperature and humidity, the product helps to reduce the manufacturing workload by eliminating the step of preparing a separate board. I²C interface support and a built-in connector allow easy wiring to the main board. The unit works in 100% relative humidity (dew point) and achieves high temperature sensing precision of ±5%. The 24x16x6.5mm sensor also houses an application-specific integrated circuit (ASIC) for temperature characteristic compensation, allowing simplification of surrounding circuits inside the equipment. It operates from 2.5 to 5.5V in the -20 to +85°C temperature range.
