The HOBO Wind Monitoring Station is an easy-to-deploy, low-cost cellular wind monitoring solution. The web-enabled HOBO MicroRX station, together with the Davis Wind Speed/Direction Smart Sensor offers long-term, reliable monitoring of wind conditions. Configurable station-side alarms provide immediate notification of critical conditions, allowing you to easily maintain OH&S compliance, and Onset's cloud-based HOBOlink platform makes it easy to view, access, and share your data.
Features:
- Integrated solar panel for easy long term deployment
- Remote access to data and current conditions with a customizable dashboard for analysis
- Alarm notifications via text/email when conditions reach user-set thresholds
- Inputs for five plug-and-play smart sensors
- Real-time monitoring with up to 10-minute connection rates via 4G cellular
