Sonic-anemo-dzp ultrasonic wind speed sensor description: Sonic-anemo-dzp ultrasonic anemometer is powered by its own solar panel. It is well suited to remote installations where power consumption matters. This unit connects directly to a pulse or potentiometer input (i.E. On davis instruments). It is a useful product for professionals, integration to aws (autonomous weather station), and well-informed users.
