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.

Automatic Water Tank Pump Switch Hardware • Microcontroller Unit: The designed circuit shown here includes an Atmega328P-PU as the kernel, a number of LEDs to display the system status, a push button ...

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.

It’s a fairly simple build, utilizing an old water jug, an Arduino, an aquarium pump, and some home-made water sensors. As always, MAKE has a very thorough guide, and the estimated build time is ...
