Weather Stations





Weather stations will be used to provide garden users with accurate, real-time data on a range of environmental conditions. Prototype weather stations, which are being tested at the sites at The Arboretum at Flagstaff, include the instrumentation listed below. Some sensors are duplicated for redundancy or testing of multiple devices. The final sensor set may include other devices. Each garden site will also include 30 WiSARD wireless sensor devices
supporting multiple soil moisture and temperature sensors (Decagon 5TM volumetric water content sensors and Decagon MPS-6 water potential sensors).
