What is the difference between Models WS-1200, WS-1200-IP, WS-1400-IP, WS-1001-WiFi and WS-1201, WS-1201-IP, WS-1401-IP, WS-1002-WiFi?
The 1st generation weather stations listed below use a alkaline rechargeable battery as the energy storage, and solar collector recharged the batteries.
The second generation weather stations below add a super capacitor as the primary energy storage device.
The super capacitor is charged by the solar collector in the day, and non-rechargeable batteries at night.
This is a more efficient and reliable design.
We recommend Lithium Energizer Ultimate batteries, because of their wide temperature range:
The second generation sensor array is compatible with the first generation sensor array.
