How to calibrate
Step 1: Point at a clear blue sky (no clouds). Press Step 1 to set the sky NIR reference using solar irradiance at your location and time (700-1100nm).
Step 2: Completely cover the camera lens with your hand or any opaque object to capture the zero reference (dark offset). Location is requested automatically on start. Press Update Location to refresh.
πΎ Calibration saved to this device. Each device stores its own calibration independently.
All reported values are incident irradiance at the filter surface (pre-filter, true scene values), not values reaching the camera sensor. Filter transmission factors (NIR: 87%, Melanopic: 4%) are applied internally.
