The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Next we connected the water flow sensor’s output to the Arduino board (filled with the sketch) and allowed water flow through the water flow sensor at a steady rate of about 1 Litre/minute. Besides ...

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 ...

“I did a bit of research, and found that different shower heads can use anywhere from 9.5 litres (2.5 gallons) per minute to less than 6 litres (1.6 gallons) per minute, if you have a flow ...

The fan nozzles are placed at a distance of 14 cm from each other and can achieve a water flow of 0.49 L/m. A 36 W DC water pump is used to bring water into the bar. “After cleaning, the used ...
