A glance at your Vantage Console tells you a lot about what the weather is doing right now, but to really understand conditions, weather data needs to be collected and analyzed, and sometimes shared. This is the sort of job computers were designed for, and the WeatherLink Data Logger Hardware is the interface between your weather station and your personal computer.  Store data in the logger to upload and display later, or use WiFi enabled accessories to constantly supply data to the Internet.

Software optimized to make sharing Weather Data simple even if you are not an Internet guru.


  • Data Logger Hardware

  • USB or Serial data cable

  • Getting Started Guide and Software on CD to load on your Computer.

Data Logger is also compatible with third party, aftermarket software. Join a weather station network or simply place your local weather data on your personal website. Track the weather at home while you are traveling.

WeatherLink hardware, software and Internet interface are backed by Davis Instrument’s world class customer support. Whether you have questions about your sensors or sharing the results on the Internet, help is just a phone-call or a web-chat away. The Davis Support team will happily direct you to an expert with years of teaching experience.
