The Apogee InSight app provides support for handheld spectroradiometers (MS-100 series) by Apogee Instruments, Inc. The Apogee spectroradiometers are self-powered, portable devices that can instantly measure and display the most important metrics for serious growers. The Apogee Insight app allows the user to take spot samples or to log light measurements over time via Bluetooth. The Apogee InSight app measures these metrics: - Illuminance (LUX)/Foot Candle (fc) - Correlated Color Temperature (CCT) - CIE Chromaticity Coordinates - CIE 1931 x, y Coordinates - CIE 1976 u’, v’ Coordinates - CIE 1931 XYZ Value - Dominant Wavelength (λd) - Color Rendering Index (CRI, Ra)/R1 to R15 - Photosynthetically Active Radiation (PAR) - PPFD (400 to 700 nm) m^-2 s^-1 - ePAR (400 to 750 nm) m^-2 s^-1 - PPF-UV (380 to 400 nm) m^-2 s^-1   - PPF-B (400 to 500 nm) m^-2 s^-1 - PPF-G (500 to 600 nm) m^-2 s^-1 - PPF-R (600 to 700 nm) m^-2 s^-1 - PPF-NIR (700 to 780 nm) m^-2 s^-1 - Percent Flicker - Spectral Power Distribution (SPD) mW/m2 - Peak Wavelength (λp) - Peak Wavelength (λpV) - Integration Time (I-Time)
