DESIGN AND REALIZATION OF A SMART WATER METER

Abstract

Measuring water consumption in each house was very difficult and that's by sending a man to gather around each house's information and report it to the company , few years later the mechanical water meter was invented it solved the distance problem , it measures the flow rate through the impeller rotation but again The mechanical water meter is no longer in optimal condition as it is unable to accurately record or retain any data. , as the technology improves this side was not forgotten and that is why an idea of working on an electronic water meter was found .This later determines the flow rate using power supply , as the water passes through the pipe it generates pulses through the rotation of the wheel and from that we determain the frequency which leads to calculating the flow rate thus the volume , with the help of STM32 MCU (for low power consumption) connecting it to a LoRa module (for a bigger distance) which sends the data obtained to a gateway , after connecting it to an MQTT server , the data collected will be stacked in the database that will be appeared on an interface.
