Lufft WS500-UMB Smart Weather Station

Area Monitoring

Weather Station Manufacturer: Lufft

Note: This unit does not record or store data internally. A telemetry device such as the Thiamis 4G is required for data logging.

The Lufft WS500-UMB is an all-in-one weather station for environmental monitoring, industrial safety, air quality networks, transportation systems, and research applications. Its integrated ventilated housing and ultrasonic wind technology provide reliable, maintenance-free measurement of five core parameters: air temperature, relative humidity, barometric pressure, wind speed, and wind direction. Measurement accuracy includes ±0.2°C temperature, ±2% RH, ±0.5 hPa barometric pressure, and ±0.3 m/s wind speed. Data is accessible via multiple protocols, UMB-ASCII, UMB-Binary, SDI-12, and MODBUS, for easy integration into monitoring networks and data loggers. External sensor inputs support optional accessories such as a rain gauge or road surface temperature probe. Features a rugged IP66-rated housing suited for long-term unattended outdoor monitoring in harsh environments.

It's an all-in-one smart weather station measuring wind speed, wind direction, air temperature, relative humidity, barometric pressure, and precipitation in a single compact sensor. It's used for fixed outdoor environmental monitoring in construction, industrial, and research applications.

The UMB (Universal Measurement Bus) digital protocol, plus analog outputs. Confirm compatibility with your data logger or monitoring platform before deploying.

Yes — it uses ultrasonic wind measurement with no moving parts, improving reliability in wet, icy, or dusty conditions compared to traditional cup anemometers. Confirm operating temperature range and protection ratings against your specific site conditions.

The WS500-UMB integrates multiple sensors into one unit, reducing installation complexity, calibration overhead, and potential failure points. It's particularly well-suited for temporary monitoring deployments and sites with limited installation infrastructure.

UMB protocol compatibility with your data logger, power supply requirements, mounting hardware needs, and whether the sensor's measurement ranges meet your project's meteorological reporting requirements.
