How do you measure how full a tank is?
Water is a precious resource in many parts of the world, and many people rely on water tanks to supplement their water supply by storing collected rainwater or water pumped from a well or bore. But how do you measure how full a tank is? Tanks are constructed of opaque material to prevent algae growth and often kept closed up to prevent mosquito infestation or access by small rodents so it’s inconvenient to physically look inside. And besides, having a way to measure tank depth electronically opens up a world of possibilities such as automatic control of pumps to top up tanks when they get low or to disable irrigation systems when not enough water is available.
In this project, the author made the water tank depth system using a differential pressure transducer and an Arduino (Ethernet). The pressure transducer measures the water pressure at the bottom of the tank, and from that to calculate how full the tank is. The Arduino then reads the output of the transducer and reports the depth of the tank. Ethernet Shield will transmit the data to the Cloud service that generates graphs of water depth over time.
