The WS300-UMB is a compact all-in-one weather sensor for measurement of temperature, relative humidity and air pressure. It is part of the WS product family of professional intelligent measuring sensors with a digital interface and an integrated design with ventilated radiation protection for various environmental applications. One external temperature or rain sensor is connectable.
SDI-12 and RS485 with supported protocols UMB-Binary, UMB-ASCII, Modbus-RTU, Modbus-ASCII, and XDR.
All-in-one housing concept of a compact weather sensor combining several measurement parameters in one housing with only a single cable connection.
