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 ...

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.

Born from the experience of the Kerala flood, TK explores how to make a simple water quality meter with a turbidity sensor. This simple project shows the theory and basic components to build a ...

I've got an Arduino/Bluetooth (Bluetooth Bee-Standalone). I've hooked it up with an HC-SR04, it's intended to be mounted at the top of a rain barrel to measure the water depth. What's the best ...

[Eric Ayars] has a nice cast iron Christmas tree stand at home, but the only drawback is that the stand makes it hard to see just how much water is available to the tree. Last year we covered a small ...

The DIY shower monitor uses a flow sensor plumbed inline with a shower head, allowing it to transmit pulses to an Arduino full cost analysis and water usage.
