Humidity sensor U11336
1. Safety instructions
In order to avoid permanent damage to the built-in
semiconductor sensor, strictly observe the following 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 applications.
2. Description
The humidity sensor is used for measuring relative
humidity (RH) and is used in conjunction with the
3B NETlog
Once connected, the sensor is automatically detected by the interface.
