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 ...

What happens when an engineer builds a smart garden? This Arduino-powered system automates watering while collecting ...

But probably the most interesting part of the project is a design for a non-invasive flow sensor that you can simply ... thanks to a power-efficient Arduino Pro Mini and a BlueTooth Low Energy ...

A sensor measures flow for the Arduino, which adjusts a control valve actuator to maintain the specified setpoint. The software uses proportional and integral control (the PI part of a PID loop).

This small sensor suitable for electronic experiments, like many others, reminds me of an automotive mass air flow sensor! (low cost anemometer wind sensor) The mass air flow (MAF) sensor in an ...
