5. Overview
The WindSonic1 is manufactured by Gill Instruments, Ltd. It is an ultrasonic anemometer for
measuring wind direction and wind speed. Two pairs of orthogonally oriented transducers sense
horizontal wind. The transducers bounce the ultrasonic signal from a hood, minimizing the
effects of transducer shadowing and flow distortion.
The WindSonic1 outputs data using the RS-232 interface. It connects to two C or U terminals or to
the CPI/RS-232 port by using an RJ45 terminal block adapter. The WindSonic1 is also compatible
with the SDM-SIO1A and SDM-SIO4A devices, which increase the number of serial sensors one
data logger can measure. The WindSonic1 is not compatible with the CR200(X)-series or CR5000
data loggers. A similar sensor, the Wind Sonic4, is compatible with the CR200(X)-series and
CR5000; refer to

for more information.
The WindSonic1 includes a user-specified cable to interface to a Campbell Scientific data logger.
A serial cable (WINDSONICRCBL-L) is available for interfacing a WindSonic1 to a computer
running the manufacturer’s computer support software. The cable and software are used during
troubleshooting or to change settings for a specific application. A copy of this computer support
software is available at

. WindView is used for WindSonic1
anemometers with serial numbers of 0810001 or greater, and WindCom is used for WindSonic1
anemometers with serial numbers that are less than 0810001.
Features:
l
Low maintenance—no moving parts significantly reduces maintenance cost and time
l
Minimum detectable wind speed of 0.01 meters per second
l
Compatible with Campbell Scientific CRBasic data loggers: CR6, CR3000, CR1000X, CR800
series, CR300 series, and CR1000
l
Compatible with the SDM-SIO1A and SDM-SIO4A serial modules, which allows one data
logger to measure more WindSonic1 anemometers
