Wind Speed & Direction Sensor Key Features Low Power Operation <2mA  Rolling Average Facility  SDI-12 V1.3 Compatible  Multiple Sensors (Maximum 10)  Solid State – Maintenance Free  2 Year Warranty  Corrosion Free  The WindSonic™ SDI-12 is a low cost anemometer, utilising Gill’s proven ultrasonic technology to provide wind speed and direction data via an SDI-12 output. New features include lower power consumption <2mA in standby and a vector or scalar rolling average feature providing 1min average and 1 min max speed with associated direction. With a robust, corrosion-free polycarbonate housing, this small, lightweight wind sensor is particularly suited to meteorological and hydrological based installations. The WindSonic™ has no moving parts, offering maintenancefree operation in a wide range of applications.
