WirelessThe wireless 5-in-1 sensor contains a self-emptying rain collector for measuring rainfall, anemometer, wind vane, temperature and humidity sensors. It is fully assembled and calibrated for easy installation. It sends data by a low power radio frequency signal (917MHz band) to the main display unit up to 150m away (line of sight).The main display shows all the weather data received from the 5-in-1 sensor outside. It remembers the data for a time range for you to monitor and analyse the weather status for the past 24 hours. It has advanced features such as the HI/LO Alert alarm which will alert the user when the set high or low weather criteria are met. The barometric pressure records are computed to give users forthcoming weather forecast and storm warning. Day and date stamps are also provided to the corresponding maximum and minimum records for each weather detail.The system also analyses the rainfall rate, and shows daily, weekly and monthly records. Wind-speed is expressed in Beaufort Scale, and readings such as wind-chill, heat Index, dew point, and comfort level are also provided
