Note: A compact analogue reflectance sensor such as the CNY70 was not used in the Arduino Uno experiments described. Instead, a homemade sensor was assembled using a single infrared LED (IR333C) and a ...

Upload this sketch to your Arduino. Now hook up the IR sensor. The IR sensor's pins are attached to Arduino as so: (from left to right with the sensor's head facing you) (Vout) Pin 1 to pin 11(Arduino ...

LEDs on the Arduino can be programmed to indicate if the sensor is/isn’t immersed by the liquid (and thus determine if liquid level is too high/low). The two companies say that the hardware provides ...
