HS 1100 / HS 1101 is a relative humidity sensor based on a unique capacitive cell. It is designed for high volume, cost sensitive applications such as office automation, automotive cabin air control, home appliances, and industrial process control systems. They are also useful in all applications where humidity compensation is needed.
The HS 1100 and HS 1101 are capacitive relative humidity sensors designed for high‑volume, cost‑sensitive applications such as office automation, automotive cabin air control, home appliances, and industrial process control. They feature full interchangeability, instantaneous desaturation, and compatibility with automated assembly processes.
Technical specifications include a wide operating temperature range, 5‑10 V supply, 0‑100 % RH measurement range, fast 5 s response time, and low humidity hysteresis. The sensors have been qualified to MIL‑STD‑750 requirements and are available in both top‑opening (HS 1100) and side‑opening (HS 1101) packages.
