The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close ... infrared light signal ...

Advances in embedded system technology—and more specifically, new sensor technology ... program. Processing also was the base for Wiring, and Wiring is the base language for Arduino.

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 ...
