Measure Total Solar Radiation

The PYR total solar radiation sensor (pyranometer) measures the solar radiation flux density (in watts per metre square) from a field of view of 180 degrees.

Measure Photosynthetically Active Radiation

The model QSO-S PAR Photon Flux sensor measures the Photosynthetic Photon Flux (PPF) in µmol m^-2 s^-1 from a field of view of 180 degrees. The diffusion disk is composed of characterized pigments for good spectral response.
