Renewable energy is gaining more attention as a new source of energy. Among all the renewable energies, kinetic energy is the most readily available energy source. One of potential kinetic energy to be utilized in energy harvesting is from the raindrop energy. The generated energy depends greatly on the size of raindrops. Therefore, it is important to study the raindrops characteristics prior for further investigation in the raindrop energy. This paper discusses the prediction of the size of raindrop based on simulated droplet using syringe pump. Edge detection segmentation method is applied to the image to detect the diameter of water droplet.
