By counting the pulses from the output of the sensor, we can easily calculate the water flow rate (in litre/hour – L/hr) using a suitable conversion formula. The Arduino Sketch (code) uses the ...

The device is built around a cheap 1/2″ brass water flow rate sensor connected to his shower hose, which outputs pulses as a small wheel passes an internal hall effect sensor. The datasheet didn ...

A series of flow sensors determine how much liquid has passed through them and, when the drink is poured, can calculate how much you poured and how much you have left. Starting with a chest ...
