When the sensor detects that the moisture content is already below 30%, it sends a signal to the Arduino, which, in turn, activates a water pump to provide hydration to the plant.

If you're looking for ways to use less water, Instructables user tamberg developed a DIY water faucet sensor that shows you when you've used up a liter. Using an Arduino, flow sensor, and colored ...

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 ...

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 ...

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 ...

A low-cost (~$100), do-it-yourself (DIY) ultrasonic water level sensor/datalogger has been designed, constructed, and tested for use in education, citizen/community science, and research settings. The ...
