Light, Solar Radiation and PAR

Loggers and meters that follow light over time: illuminance in buildings, photosynthetically active radiation (PAR) in crops, ultraviolet radiation and the direct, diffuse and global components of solar radiation.

The page includes a spectroradiometer logger that also assesses light color, an NDVI meter for spotting plant stress early, wireless PAR and lux sensors and systems that measure dust build-up on photovoltaic panels, to balance power generation against cleaning cost.
