Silicon Pyranometer HOBOnet Solar Radiation Sensor
The HOBOnet Wireless Solar Radiation (Silicon Pyranometer) Sensor is calibrated to measure light intensity for frequencies relevant for solar radiation. 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.

A complete system requires at least one HOBO RX3000 Remote Monitoring Station, a HOBOnet Wireless Manager (RXMOD-RXW-xxx), and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters (RX-RPTR-xxx) can be added to extend the range. Still, think you might need some assistance in choosing the best solution?
