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 ...

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).

It runs on an Arduino MEGA 2560 PRO (or similar microcontroller) and supports a wide array of additional hardware including pressure transducer, water level sensor, flow meter, OLED display ...

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 ...
