OVERVIEW
Keep an Eye on Your Environment from Miles Away
The HOBOnet Wireless Temperature Sensor provides a cost-effective and scalable solution for web-enabled monitoring of air temperature. HOBOnet wireless sensors communicate data directly to a HOBO RX Station or pass data through other wireless sensors back to the central station. They are preconfigured and ready to deploy, and data is accessed through the LI-COR Cloud IoT platform (formerly HOBOlink).
Features
Sensor Features
- Measurement range of -40° to 100°C (-40° to 212°F)
- High accuracy: ± 0.2°C ( ± 0.36°F)
- Stainless-steel sensor tip
Wireless Features- 900 MHz wireless mesh self-healing technology
- 450 to 600 meter (1,500 to 2,000 feet) wireless range and up to five hops
- Up to 50 wireless sensors or 336 data channels per HOBO RX station
- Simple button-push to join the HOBOnet wireless network
- Onboard memory to ensure no data loss
- Powered by rechargeable AA batteries and built-in solar panel
Important Information
Includes lithium batteries. A complete system requires a HOBO RX Station, a HOBOnet Wireless Manager, and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters can be added to extend the range of both system options.
