This sensor is relatively complex to set up, but it works with older Arduino boards like the first-gen Uno. Measuring the pH level of a water source can give you a range of information about the ...

They feature analog pins for reading analog components (e.g., potentiometer, flex sensor, pH sensor ... come across the Uno and Nano. They're two of the most frequently used Arduino variations ...

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 ...
