Plant Health monitoring is one amongst the foremost important tasks in any agriculture-based environment. India is one among the nations where agriculture and allied sectors are major employment sources. Thus, there have to be an efficient system for monitoring plant health condition and also for spraying of chemicals to plants. This paper aims at the monitoring of plant health condition supported color prediction calculation which helps in recognizing the difference between the healthy and non-healthy plants. This will be done by calculating HSN color values of plant leaves. The pictures of the plant are taken from the pi camera which is interfaced with the Raspberry pi. The raspberry pi is coded with the python to capture images and calculating color ratios. We have a robot which can move in multi-direction and controlled over wireless using Wi-Fi, the same robot has raspberry pi with the camera installed which is employed to detect the crop.
