Lufft WS-800

Multiparameter weather sensor

ws800 weather sensor

Integrated design with ventilated radiation protection for measuring: Air temperature, relative humidity, precipitation intensity, precipitation type, precipitation quantity, solar radiation, lightning detection, air pressure, wind direction and wind speed. One external temperature sensor is connectable.

  • First and only all-in-one compact weather sensor with lightning detection
  • Built-in data pre-processing, universal interfaces and selectable output protocols
  • SDI-12 and RS485 interfaces
  • Maintenance-free operation – no moving parts to wear out
  • Suitable for all climate zones; also for solar-powered automatic meteorological stations
  • Integrated heater that can be switched on if there is danger of frost

What's the Easiest and Quickest Way to Start Collecting Data and Access it Anywhere?

The Answer's in the Cloud.

eTracker is a cellular modem and "virtual" cloud-based data logger in one (meaning you don't need to install a separate data logger). Simply connect your sensor and a power source to eTracker and you're done. Configure (or reconfigure) anytime from any Internet-connected device, and use Stevens-Connect to retrieve your data, or forward it to your favorite software system.
