Summary: The objectives of this project were: 1. Construct, sell, install, and service about 50 FST sensors for Beta testing. Some sensors will be used with the self-contained system (i.e. sensor that transmits to a portable receiver unit) and some with “local networks” of the AgWeatherNetwork stations. 2. Construct, install, and service FST sensors on the Beta sites of the AgWeatherNetwork system. These sensors will be loaned for use at these Beta sites during 2005. 3. Continue research with different controllers and timer systems to identify reliable systems at a reasonable cost. 4. Continue research, if needed, to improve the FST sensors. Study reliability and life of the sensors and control systems. 5. Conduct studies to learn more about spatial variability within an orchard. 6. Continue search for cost-effective manufacturer, distributor, and retailers
