Deskripsi

Overview

Davis® Wind Speed/Direction Smart Sensors are compatible with all HOBO weather station loggers, HOBOware, and HOBOlink. They offer the same ease-of-use as existing Onset Smart Sensors, providing cost-effective HOBO weather stations for projects on a tight budget.  The sensors feature a plug-in modular connector for easy installation, and all configuration parameters are stored in the sensor and automatically communicated to the logger, eliminating the need for programming or extensive setup.
