Overview
The WS700-UMB is an all-in-one weather sensor with measurement of temperature, relative humidity, precipitation intensity, precipitation type, precipitation quantity, air pressure, wind direction, wind speed and radiation. 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 sensor is connectable.
Benefits
All-in-one housing concept of a compact weather sensor combining several measurement parameters in one housing with only a single cable connection.
Maintenance free operation as there are no moving parts that can wear out. Precipitation is measured with a radar sensor.
SDI-12 and RS485 with supported protocols UMB-Binary, UMB-ASCII, Modbus-RTU, Modbus-ASCII, and XDR.
