The SR10 Series Solar Radiation Sensors from Environdata Australia are general purpose items with cosine correction. They are designed for recording hours of sunshine as well as total incident solar energy and are suitable for applications like Agricultural, Irrigation management, Meteorological projects, Bush fire management, and Solar Radiation Intensity.

The solar radiation sensors’ cosine correction is achieved by shaping a teflon diffuser and accurately housing this inside an opaque cylinder. A silicon photovoltaic cell is mounted inside the diffuser. This combination provides a standardised reading equivalent to radiation falling on a non-reflective flat surface.

For clear unobstructed daylight conditions, the SR10 Series Solar Radiation Sensors compare favourably with first class thermopile-type pyranometers. The spectral response of the Environdata pyranometer does not cover the full range of the solar spectrum, but the error introduced is under ±5% under most natural daylight conditions.

When recording under vegetation or artificial lights, readings from the SR10 Series Solar Radiation Sensors should not be taken as absolute. The top of the sensor should be cleaned of dust with a tissue as a routine maintenance task.
