The HOBOnet Wireless Photosynthetic Active Radiation (PAR) Sensor measures light intensity for frequencies relevant to photosynthesis. HOBOnet Wireless Sensors communicate data directly to the RX3000 weather 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.


Highlighted Features

Sensor Features

  • Measurement range of 0 to 2500 umol/m2/sec over wavelengths from 400 to 700 nm

  • Enclosed in an anodized aluminum housing with acrylic diffuser


Wireless Features

  • 922 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 per RX3000

  • 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

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 (RX-RPTR-xxx or RXW-RPTR-B-xxx) can be added to extend the range.
