Water leakage Detection system using Arduino
This project aims to detect leakage water in hospitals, buildings, industrial areas and plants. Using this system we can find out exact leakage point for underground pipe system. We can also measure flow rate and volume of water pass through pipe.
In this project I used Arduino Uno, YFS201 Hall effect Water flow sensors, 16x2 LCD, Water pipes, connecting wires.
In this project we will interface YFS201 Water flow sensors with Arduino. We use two hall effect sensor at end of pipe. When their is pipe leakage inside pipe, then we get flow rate difference between inlet and outlet of pipe. This difference measure and displayed on LCD screen.
YFS201 Flow sensor
In water flow sensor hall effect sensor is used. When wheel inside this sensor is start moving, this provide the high and low pulse. This pulses are calculate and we get the flow rate of sensors. We connected the sensor output pins on A0 and A1 pins of Arduino uno.
