Wireless Weather Stations
Monitor nine different weather conditions up to 1,000 feet away. The outdoor weather sensor measures outdoor temperature, humidity, wind speed and direction, rainfall rate, total rainfall, barometric pressure, heat index, wind chill, and dew point. It wirelessly transmits readings to the console by radio signal. Console has built-in sensors to measure indoor temperature and humidity. Console can be placed on a desk or mounted to a wall. They cannot be sold to the listed areas due to product registration requirements.
