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 ...

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.

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 ...

Using an Arduino, flow sensor, and colored LEDs, tamberg set up the device to change colors from blue to red when a liter has been used up. For simple tasks, like washing your hands, a Liter is ...

We’ve seen several water flow measurement systems for home use, such as this neat ESP8266-based shower water monitor. If you prefer just a simple visual reminder to turn off the tap, have a look ...
