SR05

The SR05, manufactured by Hukseflux Thermal Sensors as the SR05-D1A3, is an ISO 9060:2018 spectrally flat Class C (second class) pyranometer designed for general solar radiation measurements in agricultural and meteorological networks and PV monitoring. Both analog output and Modbus over RS-485 are supported.

The SR05 measures solar radiation received by a plane surface, in W/m², from a 180° field of view angle with a high-quality blackened thermopile protected by a glass dome. The blackened thermopile provides a flat spectral response for the full solar spectrum range, which allows the SR05 to be used under plant canopies or lamps, when the sky is cloudy, and for reflected radiation measurements.

The SR05 produces two different outputs that are measured directly by a Campbell Scientific data logger: a 0 to 1000 mV signal and a Modbus over RS-485 signal.
