Many home weather stations suffer accuracy problems because the sensors need to be mounted near structures or trees. The Oregon Scientific WMR300 Ultra Precision instrument suite has a wireless range of 300m (1000’!) so the instruments can be mounted on a dedicated pole far away from any interference, while you read the monitor the results from the comfort of your desk. The rain gauge, anemometer, temperature & humidity sensors and their transmitters are solar powered (with battery backup), so the readings will be consistent with little maintenance required.

Simple to set-up sensor suite and easy to read and informative base station

Enjoy accurate timekeeping as the unit aligns itself with the US Atomic Clock. The easy to read base station displays indoor and outdoor temperature & humidity, wind chill & heat index readings, UV Index, Wind direction and speed, weather prediction data, sunrise/sunset & moon phase, rainfall trends, barometric data and rainfall rates. The touch screen interface is simple to program.

Includes exclusive Weather OS Pro software, a highly intuitive, customizable PC interface which will allow you to upload, manage, analyze and share weather data. Connect with other weather observers on social media to coordinate data and study regional weather trends.
