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 ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

The example project Arduino Bin Level Sensor presented here incorporates a simpe force sensitive resistor (FSR) for monitoring common bins with solids and some liquids whether conductive or ...
