RainWise MK III Weather Transmitter

The MK III roof top sensor assembly is wireless and solar powered with a range of up to 400 feet. The MK III sensor assembly broadcasts the weather data to an indoor receiver and a computer interface. The MK III measures wind speed, wind direction, temperature, barometric pressure, and relative humidity. The system also calculates wind chill, dew point, heat index, and daily maximums and minimums.

Following are the instrument specifications:
