The ALTA Wireless PAR Light Meter uses a blue-enhanced silicon photodiode to measure the specific wavelengths of light that plants need for photosynthesis based on a user-configurable time interval or Heartbeat. The PAR Light Meter measures Photosynthetic Photon Flux Density (PPFD) in µmol/m2/s. PPFD is the amount of PAR light (photons) that arrive at the plant's surface each second. The PPFD measurement is integrated throughout the day to produce the Daily Light Integral (DLI) in mol/m2/day.

The PAR Light Meter resets the DLI accumulation at a customer-configurable time of day.
