The Arduino Sketch (code) uses the external interrupt ... time through the water flow sensor it was first passed through the water flow sensor which was taken as input interface in the flow. Formulas ...

The nano sensor interface presented below is a microcontroller-based universal sensor interface with a power-saver mechanism. The idea, centered around an Arduino Nano (v3) microcontroller, was ...

A sensor measures flow for the Arduino ... and used a user interface more suited for the Arduino and gotten a better result. Don’t get us wrong. PLCs have a place. So do Arduinos.
