Oregon Scientific UVN800 Ultra-Violet Index Sensor is compatible with the WMR90A, WMR100 and WMR200. It collects UV data and records a risk message that indicates when it was noted. It has a transmission range of up to 330 feet (100 meters) and is wall mountable or stake mountable.
For longer life and use in colder climates, we recommend Lithium batteries. Standard Alkaline batteries contain significant amounts of water. Because of this they will freeze in low temperatures of approximately 10 F (-12 C). Consumer grade Lithium batteries have a much lower threshold for temperature with an estimated freezing range of below -22 F (-30 C).
