WATER FLOW SENSOR/ FLUID FLOW METER CONTROL SWITCH SENSOR IN INDIA

Water flow sensor can be used to measure the flow of liquids (i.e. the consumption of liquids in industrial or domestic use). For example, you can make a robotic cocktail dispensing machine, and can use this sensor to accurately measure components like Soda, Water, etc. Water flow sensor consists of a plastic valve body, a rotor, and a hall-effect sensor. When water flows through the rotor, the rotor rotates and its speed changes with different flow rate. The hall-effect sensor outputs the corresponding Signal pulse. It is very simple to use, you just need to connect the PWM output to the Arduino interrupt pin 2, and can measure the number of PWM pulse/interrupt per unit of time. The water flow would be directly proportional to the number of pulses measured. Connection: Red wire: +5V Black wire: GND Yellow wire: PWM signal
