The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module ... GND of the module is the common (0V) connection. The digital signal ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

The sensor has to be submerged in the water for this to work properly. Arduino leak sensors only have three pins to connect ... boards like the first-gen Uno. Measuring the pH level of a water ...
