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 ...

There is no official support, but there are wiring guides and sources aplenty from which to purchase the various optional parts. It runs on an Arduino ... water level sensor, flow meter, OLED ...

Recently I vowed to keep my plants alive, so I turned to Arduino ... soil resists the flow of electricity, which tells you how moist it is. Adding a photoresistor (light sensor) and a thermistor ...

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).
