Wireless Weather Station, Solar Powered

Features:

• Power is provided by an efficient photovoltaic module (PVM) and microelectronic management system fueled by ambient light (solar)
• Weather data transmitted from the weather station is stored by the controllers and reviewable by LEIT RC2ET handsets
• The weather station ID number enables any controller in range to differentiate among multiple weather stations allowing the controller to receive information from several weather stations
• Based on user input and information collected from the weather station sensors, a LEIT-2ET controller performs the calculations needed to override or adjust the daily scheduled irrigation program to compensate for evapotranspiration (ET)
• Environmentally friendly, utilizes RoHS compliant components
• The LEIT weather stations utilize radio frequency in the ISM band 902-928 MHz (866 Hong Kong, 868 International) CE, IC, FCC certified, Australia and Hong Kong compliant
• The LEIT weather station's electronic components and sensors are completely waterproof
• The rain gauge is a self-emptying tipping bucket reading rainfall in 0.01 inch increments
• The LEIT weather station's three-plate radiation shield is specially designed to protect the sensors from reflected and radiated heat
• The LEIT WWS and WWSE weather stations can provide information to the LEIT ET controllers to completely stop irrigation if it is raining, freezing or too windy
• Current weather data is provided to LEIT-2ET controllers daily, every hour, during daylight hours only
• The weather stations function both day and night in any weather and in most outdoor locations and only transfer weather data during daylight hours
• Rugged and lightweight plastic construction
• Three-year manufacturer's warranty
