Sonic-anemo-sdi ultrasonic wind speed sensor description Sonic-anemo-sdi is made from the cv7-v to which a sdi12 protocol and optimizing electrical consumption has been added. Sample rate is 2 hz. This ultrasonic wind sensor operates in a request-response mode. This product is more energy-efficient than standard units. The sonic-anemo-sdi is dedicated to meteorological applications. Sonic-anemo-sdi ultrasonic wind speed sensor available data: - average speed and direction over 10 minutes - minimum wind speed and direction for that period - maximum wind speed (gust 3s) and direction for that period - software version and serial number - data measurement quality rate from the sensor - data for sensor diagnostic (manufacturer use only) Sonic-anemo-sdi ultrasonic wind speed sensor specification: * output data format: sdi-12 v1.3 * information transmited: inst.
