Lufft WS-500

Multiparameter weather sensor

ws500 weather sensor

Integrated design with ventilated radiation protection for measuring: Air temperature, relative humidity, air pressure, wind direction and wind speed. One external temperature or rain sensor is connectable.

  • All-in-one housing concept of a compact weather sensor combining 5 measurement parameters in one housing with only one cable connection
  • Built-in data pre-processing, universal interfaces and selectable output protocols
  • SDI-12 and RS485 interfaces
  • Maintenance-free – no moving parts to wear out
  • Ventilated temperature and humidity measurement according to WMO guidelines
  • 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.
