Key features
- All-in-one housing concept of a compact weather sensor combining several measurement parameters in one housing with only one cable connection
- Tiltable pyranometer as part of the sensor unit
- Built-in data pre-processing, universal interfaces and selectable output protocols
- Maintenance-free operation – no moving parts that can wear out
- Compatible with many commercially available Met/HydroMet data loggers and PLS systems thanks to an open communication protocol
- Suitable for all climate zones; also for solar-powered automatic meteorological stations
- Ventilated temperature and humidity measurement according to WMO guidelines
The WS304-UMB Smart Weather Sensor for measuring of air temperature, relative humidity, solar radiation, air pressure. Relative humidity is measured by means of a capacitive sensor element; a precision NTC measuring element is used to measure air temperature. Measurement output can be accessed by the following protocols: UMB-Binary, UMB-ASCII, SDI-12, MODBUS. One external temperature or rain sensor is connectable.
