IOT based Smart Flow Meter for Smart Cities

Abstract

Nowadays world is facing many serious problems. Water scarcity is one of the major issues which affects almost 4 billion people across the world. Proposed idea contributes to conserve water. It introduces an IoT based system which can calculate exact water usage of specific houses. Concept of smart flow meter implies the measurement of fluid volume consumed by the user and this usage is monitored and displayed to the corresponding user. Once a certain limit of usage is passed then the customer will receive a text message or a mail as a warning or reminder. After that charges will be applied for each liter of water used by that family or a specific person. The volume of water used is detected by ultrasonic sensors where micro-controllers receive the input data and send it to customers via text message through GSM module. If this system is implemented in every house and society then it will help significantly to reduce wastage of water and water scarcity for all smart cities.
