Your local news service can give you up to the minute reports of conditions at the local TV station, or perhaps the airport, but you need to know what is happening in the microclimate where you are. The base station of the Oregon Scientific WMR200A wirelessly reads the conditions from a sensor suite mounted within 300 ft, giving you data from up to ten sensors, including wind speed and direction.

Simple set up and can be interfaced with your computer.

The base station displays current weather conditions, moon phase, and precise time coordinated with the US Atomic Clock. Measures indoor and outdoor temperature and humidity, as well as dew point, wind chill and heat index. Barometric pressure along with wind speed and direction allow for accurate amateur forecasting.

The base station display has battery backup, allowing it to be repositioned without losing data. Includes a 6’ usb cable to interface with your home computer to record data and observe weather trends. Readings in the data logger are time stamped.
