… our personal weather station ( PWS ) reporting to Wundergound and Ambient networks. The WS-1002-WiFi uses a super capacitor for energy storage, and is charged by the solar collector in the day, and non-rechargeable batteries at night. It is accurate, precise, and affordably priced. It transmits 915MHz from the outdoor sensor array and indoor temperature sensor to the display console. We have it mounted on the goat shack.
