Supplementary description:

WS401-UMB Smart Weather Sensor for measuring of air temperature, relative humidity, precipitation and air pressure. Relative humidity is measured by means of a capacitive sensor element; a precision NTC measuring element is used to measure air temperature. Optionally, the WS401-UMB can be equipped with a leaf wetness sensor in addition. Precipitation is measured by tipping spoon and tipping bucket processes. The flexible tipping bucket allows a 0.2mm or a 0.5mm resolution of the rainfall. Measurement output can be accessed by the following protocolls: UMB-Binary, UMB-ASCII, SDI-12, MODBUS. One external temperature sensor is connectable.

Special features:

  • Aspirated temperature/humidity measurement
  • Open communication protocol:
  • UMB-ASCII
  • UMB-Binary
  • SDI-12
  • MODBUS
  • Analoge outputs in combination with 8160.UDAC
