Outdoor sensor (backup)
The primary power source for the outdoor sensor is the solar panel. When
available solar power (light over recent period) is insufficient, the batteries
will be used. In outdoor climates that frequently have sustained temperatures
below 0° C (or 32° F) the use of Lithium batteries is strongly suggested as
these are performing better than Alkaline batteries under such circumstances.
