I'm interested in analyzing plant status and want to check with my technology.
So I searched 'Infragram' project which is developed in Public Lab(https://publiclab.org/) and it is work as below.

Vineyards, large farms, and NASA all use near-infrared photography for assessing plant health, usually by mounting expensive sensors on airplanes and satellites. At Public Lab developed a Do-It-Yourself way to take these kinds of photos, enabling us to monitor our environment through quantifiable data.

Their technique uses a modified digital camera to capture near-infrared and blue light in the same image, but in different color channels. We then post-process the image (using Infragram.org) to attempt to infer how much it is photosynthesizing. This allows us to better understand and quantify how much of the available light plants are metabolizing into sugar via photosy
