All living organisms need water for their survival. About 98% of the Earth’s fresh water is groundwater. To avoid scarcity, proper rain water harvesting structures need to be built in rain fed areas. However, the effectiveness of such structures can be assessed only by measuring the water recharge rate of the ground water sources like open wells and bore wells. The current work envisages the provision of a low cost long-term, continuous measurement and data logging of ground water level. In order to measure the ground water recharge, a pipe of thinner diameter is immersed into the water body (well) with pressure sensor mounted at the top. The back pressure developed in the small tube is proportional to the height of the water column inside the tube. This is measured at regular intervals and a Raspberry Pi webserver is used as data logger for long time storage. The data analysis of the stored data facilitates the water recharge capability of the well or bore well thereby indirectly measures the efficacy of the water harvesting structures in the nearby areas. Keywords: digital pressure sensor; Raspberry Pi; level measurement; ground water recharge. Reference to this paper should be made as follows: Mary, X.A., Rose, L. and Rajasekaran, K.
