Monitoring environmental conditions allows farmers to have more control over the risks they face due to the weather.
Systems can range from a simple rain gauge to a fully featured agricultural weather station with data automatically uploaded to the web. Commonly used sensors measure soil moisture, soil temperature or rainfall while comprehensive systems are able to calculate values such as Potential Evapotranspiration and Growing Degree Days. Specific applications include the use of soil moisture to manage irrigation, recording (logging) of flow meters and monitoring of wind speed and delta T for spray operations.
