of water that has passed through the pipe. Water flow is measured in liters per hour or cubic meters.
Working:
A water flow sensor is made up of a plastic valve through which water can pass. A water rotor and a hall effect sensor are used to sense and measure the flow of water.
When water flows through the valve, it causes the rotor to rotate. The motor's speed can be changed as a result of this. The hall effect sensor calculates this change and outputs it as a pulse signal. The rate of flow of water can thus be measured.
The Hall effect is the primary operating principle of this sensor. The rotation of the rotor induces a voltage difference in the conductor in this sensor, according to this principle. This induced voltage difference runs in the opposite direction of the electric current. When the moving fan rotates due to the flow of water, the rotor rotates, inducing a voltage. The hall effect sensor measures the induced voltage and displays it on the LCD display.

The water flow sensor can be used with hot, cold, or warm water, as well as clean or dirty water. A microcontroller board such as Arduino , Raspberry pi, a LCD display or OLED Display , Breadboard and connecting wires are required for this. The sensor is installed at the water source inlet or the pipe opening. Three wires are connected to the sensor. The red wire connects to the supply voltage. A black wire connects to the ground, and a yellow wire collects the Hall effect sensor output. 5V to 18V DC is required for supply voltage.
Connection details:
Red wire : +5V
Black wire : GND
Yellow wire : PWM output.
