Note: Batteries for the ultrasonic anemometer are not
included. You will need 2 AA size Lithium
battery for the ultrasonic anemometer, which is
primarily for startup and backup purpose.
After setup and during normal operation, the
unit is getting its power from solar cell.
Note: There’s a built-in heat plate in the 6-in-1 sensor
package body, if the lowest temperature at
your place is below -3°C, or 26.6°F , and the
weather is mostly snowy or rainy, then you
may need to activate the heater by supplying
an external 5V/1A power to the sensor heating
element for melting accumulated snow or ice,
which can influence wind measurement
accuracy significantly. Please contact us at
support@ecowitt.com for the extension cord
information if needed.
