Faucet add-on Water Supply Management System using Smart Sensors

Due to growing demands of water in the upcoming years and with many countries severely impacted by water crises today, we would need a more efficient system than traditional techniques of domestic water management. This paper aims at developing an efficient and cost effective method of placing an upper limit on the amount of water used daily. Our prototype is a faucet device which has two modes of operation: running mode and filling mode. User is pre-alarmed when more than optimum water amount is being dispensed. In order to do this, we have embedded an algorithm that integrates functions such as data acquisition and data management in a microcontroller that dynamically computes and compares the amount of water being dispensed through the flow sensor, with ideally required water amount for the two modes of operation. The proposed design is a strategy which will also help the user to keep a check on the amount of water leaking from the faucet, promoting smart planning for healthy and sustainable water management. This novel monitoring approach is inexpensive which also saves affluent quantity of water.
