The RK200-03 Pyranometer sensor measures solar radiation. It is suitable to be used to monitor solar activity in solar parks, solar-dependent systems, and others. In order to reduce the ambient temperature effect, a temperature compensation circuit is built into the sensor.

The form factor of the Sensor Hub allows for multiple and/or different sensors to be connected at the same time as well as a solar panel, creating a reliable solar-powered solution.
This solution is suitable in scenarios where solar energy is preferred/needed.
The Splitter cable can connect several Sensor Probes and Probe IOs to a single Sensor Hub port to be powered by the solar power source. The distance between the Sensor Hub and Sensor Probe/Probe IO can be extended via the Extension cable.
