This project demonstrates a simple water detection system using an Arduino board and a water sensor. The system uses an LED to indicate whether water is detected. The LED turns ON when no water is ...

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 ...

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 ...

Simply connect the moisture sensor and the water pump (through the relay) to the Nano RP2040 Connect board, insert the moisture sensor in a flower pot, and put the pump in a recipient filled with ...

As such, I'd like to build myself some wireless moisture sensors for moderate scale production (consider 50 test points reasonable).
