Table 12: Power specification
The primary power source for the anemometer sensor is the solar panel.
When available solar power (light over recent period) is insufficient, the
battery 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.
