OVERVIEW
Monitor conditions from anywhere with HOBOnet Temperature Sensor
A cost-effective and scalable solution for web-enabled monitoring of air, soil, and water temperatures. The LI-COR Cloud IoT platform (formerly HOBOlink) wireless sensors communicate data directly to the HOBO RX3000 or the HOBO MicroRX 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 LI-COR’s Cloud IoT platform.
Highlighted 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
- Sensor and cable rated for immersion in water or soil up to 50°C for up to 1 year
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

Important Information
A complete system requires at least one HOBO RX3000 Remote Monitoring Station, a HOBOnet Wireless Manager, and a HOBOnet Wireless Sensor, OR one HOBO MicroRX Station (which has an integrated HOBOnet Wireless Manager) and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters (RXW-RPTR-xxx or RXW-RPTR-B-xxx) can be added to extend the range.
