WS303-UMB Smart Weather Sensor




From the WS product family of professional intelligent measurement transducers with digital interface for environmental applications.

Supplementary description:

WS303-UMB Smart Weather Sensor for measuring of air temperature, relative humidity, solar radiation, air pressure. Relative humidity is measured by means of a capacitive sensor element; a precision NTC measuring element is used to measure air temperature. The world renowned technology of Kipp+Zonen CMP3 is integrated. Measurement output can be accessed by the following protocolls: UMB-Binary, UMB-ASCII, SDI-12, MODBUS. One external temperature or rain sensor is connectable.
