All-in-one weather sensor WS301

air temperaturerelative humidity

The WS301-UMB is a compact all-in-one weather sensor for measurement of temperature, relative humidity, radiation (spectral flat Class C, K&Z CMP3) and air pressure. It is part of the WS product family of professional intelligent measurement transducers with a digital interface for environmental applications. It has an integrated design with ventilated radiation protection. One external temperature or rain sensor is connectable. Benefits Maintenance-free operation Maintenance free operation as there are no moving parts that can wear out. Spectrally flat Class C Pyranometer Flexible interfaces and telegrams SDI-12 and RS485 with supported protocols UMB-Binary, UMB-ASCII, Modbus-RTU, Modbus-ASCII, and XDR.
