VERNIER PAR SENSOR
Vernier's PAR (Photosynthetically Active Radiation) Sensor measures photosynthetic light levels in both air and water.
The sensor reports the Photosynthetic Photon Flux Density (PPFD) which corresponds to micromoles of photons per meter squared per second (μmol m-2 s-1). This is the power of electromagnetic radiation in the spectral range that is used by plants for photosynthesis (400–700 nm).

The PAR sensor features a waterproof sensor head and can be used to measure PPFD from sunlight and electric light sources. Ideal for experiments investigating photosynthesis and primary productivity, the Vernier PAR sensor can be used in many agricultural and environmental science applications

Requirements:
This sensor requires suitable software and an interface such as one of the Vernier LabQuest variations or Vernier Go-Link.
