We developed 4S to monitor vegetation indices, fPAR and LAI concurrently, continuously. We integrated LED spectral sensors, micro-computer, micro-controller, Raspberry Pi cameras with internet modules. This is highly flexible system which enables to add new components easily. All source scripts are available via Jongmin’s Github link below.
