RK120-09D wind speed and direction meter is a kind of measuring instrument which uses the time difference of ultrasonic wave in the air to measure the wind speed and direction.It uses low-power chip with power consumption of only 0.2W, which is especially suitable for solar or battery powered environment with high power consumption requirements. Due to the adoption of new technology and new process, the structure is more compact and compact.This model is customized to be completely compatible with Davis Vantage Pro2 series weather station, can be directly connected to Davis ISS via RJ11 port.Wind speed is pulse signal, wind direction is potentiometer signal, which can completely replace ා#7911, #7913,#7914,#6410 from Davis.
