air temperatureprecipitationrelative humidity

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. Benefits Aspirated radiation shield Flexible interfaces and telegrams SDI-12 and RS485 with supported protocols UMB-Binary, UMB-ASCII, Modbus-RTU, Modbus-ASCII, and XDR. All-in-one housing concept & easy installation All-in-one housing concept of a compact weather sensor combining several measurement parameters in one housing with only a single cable connection.
