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 HOBOlink, Onset’s innovative cloud-based software platform.
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.
