Internet of Things and Image processing have been so far applied for various applications. Their application in the field of agriculture has achieved a certain degree of success, however, the combination of both these technologies so far is non-existent. This paper describes an approach to combine loT and image processing in order to determine the environmental factor or man-made factor (pesticides/fertilizers) which is specifically restricting the growth of the plant. Using an IoT sensing network the readings of the crucial environmental factors and the image of the leaf lattice is processed under MATLAB software by the help of histogram analysis to arrive at optimal results.
