Ultrasonic anemometer6415
Ultrasonic anemometers have their own solar panels, so they do not require an external power source.
It can work with EnviroMonitor ® Nodes can be used together to add wind data to the EnviroMonitor system, or substitute anemometers can be added to the Davis weather station. It is installed in the sensor transmitter and when connected to WeatherLink Live ™ When reporting, it can be used to include multiple other weather stations in the existing system.
