Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

Since this project uses a water flow sensor containing a Hall-Effect sensor that outputs a pulse rate proportional to flow rate, so not only is it a useful project in its own right but it also ...

While this is a cool project, as a pool owner I'm not sure you'll find it worth the effort. My water level maintenance consists of dropping a garden hose in the pool and letting it run for 30 ...

This weekend’s Make project is a great one for pet owners — an automatic water bowl refilling device! It’s a fairly simple build, utilizing an old water jug, an Arduino, an aquari… ...

It will switch off only after the water drops below level A. Figure 2 illustrates the complete circuit. Using a rail-to-rail op amp for U2 allows for the application of a single 5-V power supply.
