Humidity sensor U11336
Instruction sheet
10/08 WH
1. Safety instructions
In order to avoid permanent damage to the built-in
semiconductor sensor, strictly observe the follow-
ing instructions:
•
Never exceed the maximum operating tem-
perature of +85°C.
•
Do not allow the semiconductor sensor to
come into contact with water. Do not expose
the semiconductor sensor to direct sunlight.
The humidity sensor is not suited for safety appli-
cations.
2. Description
The humidity sensor is used for measuring relative
humidity (RH) and is used in conjunction with the
3B NETlog
TM interface (U11300).
Once connected, the sensor is automatically de-
tected by the interface.
