Overview
The LI190SB, manufactured by LI-COR, is a quantum sensor that accurately monitors Photosynthetic Photon Flux Density (PPFD) in both natural and artificial light. It connects directly to our data loggers and is ideal for growth chambers and greenhouses.
Key Advantages
Compatible with most Campbell dataloggers and wireless systems
Technical Description
The LI190SB measures solar radiation with a silicon photovoltaic detector mounted in a cosine-corrected head. A shunt resistor in the sensor’s cable converts the signal from microamps to millivolts, allowing the LI190SB to be measured directly by a Campbell Scientific data logger.
LI190SB accurately measures Photosynthetic Photon Flux Density (PPFD), which is the number of photons in the 400 to 700 nm waveband incident per unit time on a unit surface. Because PPFD describes photosynthetic activity, the LI190SB is ideal for growth chambers and greenhouses.
