To ensure accuracy, each sensor is carefully calibrated under controlled conditions. The sensor integrates silicon photodiodes and customized filters. Typical applications include PPFD / par measurement of plant canopy in outdoor environment, greenhouse and growing room. The measurement results can be viewed on OLED display.
