In this paper we will investigate which parameters are important for energy harvesting from raindrops through a piezo based sensor. We will make a chamber filled with fluid or gas and a membrane to cover the chamber. Then connect the piezo based pressure sensor to the chamber so we can register how much pressure/energy can be gained from a drop. Then we will investigate which parameters are important such as: the drop height, drop frequency, drop size and finally we will give an estimate on how much energy can be obtained from a drop.
