The smart water meter enables efficient monitoring and measurement of water usage in households or industries. It collects real-time data on water consumption and can be integrated with an app or display for tracking usage patterns. The project provides a modern solution for water conservation by allowing users to monitor their water consumption and identify wasteful usage habits.
 
How the Project Works:
 
      The smart water meter uses a flow sensor to measure the amount of water flowing through a pipe. The data collected by the sensor is processed by a microcontroller, which can display real-time water usage on an LCD screen or send the data to a remote server or mobile app for logging and analysis. The user can monitor daily, weekly, and monthly water usage trends.
 
Components List:
 
Microcontroller (Choose One):
Arduino Uno (for basic functionality and ease of use).
Arduino Nano (for a compact design).
ESP32 (for Wi-Fi connectivity and remote data logging).
ESP8266 (for basic IoT functionality at a lower cost).
Raspberry Pi Pico (cost-effective for basic real-time monitoring).
Flow Sensor:
YF-S201 Water Flow Sensor: Measures the water flow rate and sends pulses proportional to the flow rate to the microcontroller.
Display:
16x2 LCD (for showing real-time water usage on a local display).
Connectivity (Optional for IoT Variant):
Wi-Fi Module (ESP32/ESP8266): For remote data logging and access through a mobile app or web dashboard.
Power Supply:
5V Power Supply: Can be powered via USB or a battery pack.
Prototyping Components:
Breadboard for prototyping.
Jumper wires for connecting components.
 
Working Guide:
Water Flow Measurement: The flow sensor is installed in a water pipe. As water flows, the sensor generates pulses based on the flow rate.
Data Processing: The microcontroller counts the pulses and calculates the water flow rate and total water usage.
Data Display: The LCD screen shows the real-time water usage in liters per minute and total consumption.
Optional IoT Feature: With ESP32 or ESP8266, the data can be sent to a server or cloud platform, where users can access their water consumption data from anywhere via a web or mobile app.
Monitoring and Alerts: The system can be set up to provide alerts when water usage exceeds a certain threshold, helping users conserve water.
