Description
Accurately calibrated, digital humidity-temperature module with I²C
interface. The sensor is dew resistant, temperature compensated,
shows a very low hyteresis, negligible long term drift and linearity
errors. Up to 112 addresses on the same bus line. It is mechanically
robust, easy exchangeable and chemically resistant. The module
features a high quality micro system on ceramic substrate using a
polymer capacitive humidity sensor. The TO-39 housing with steel
mesh filter is suitable among others for the use in medical devices and
dryer systems.
Attention
Please avoid extreme mechanical and inappropriate exposure.
The device/product is not suitable for potential explosive areas and
medical-technical applications.
