3.There’s a built-in heat plate in the 7-in-1 sensor
package body, if the lowest temperature at your place
is below 0°C, or 32°F, and the weather is mostly
snowy or rainy, then you may need to activate the
heater by supplying an external 12V/1A power to the
sensor heating element for melting accumulated snow
or ice, which can influence wind measurement
accuracy significantly. Please contact us at
