Power Specification
USB gateway 5V DC
Outdoor sensor Solar panel (built-in)
Outdoor sensor (backup) 2 x AA 1.5V LR6 Alkaline (not included), or
2 x AA 1.5V Lithium battery (not included)
Table 8: Power specification
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.
