The WS401 Weather Sensor measures air temperature / relative humidity / air pressure / precipitation.
From the WS product family of professional intelligent measurement transducers with digital interface for environmental applications. It has an Integrated design with ventilated radiation protection.
Model: 8377-U01
Relative humidity is measured by means of a capacitive sensor element; a precision NTC measuring element is used to measure air temperature. Optionally, the WS401-UMB can be equipped with a leaf wetness sensor in addition. Precipitation is measured by tipping spoon and tipping bucket processes. The flexible tipping bucket allows a 0.2mm or a 0.5mm resolution of the rainfall.
Measurement output can be accessed by the following protocols:
UMB-Binary, UMB-ASCII, SDI-12, MODBUS.
