IR Sensor Operation: The IR sensor emits infrared light from an LED and detects the reflected light with a photodiode. When an object comes within the sensor's range, the amount of reflected light ...

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 ...

“Muxall open source Infrared Detector (IRD) for reflective sensing, light curtains, and fast proximity applications. Works with Arduino (5V) and Raspberry Pi (3.3V) TTL.” ...

This sensor gives logic high (H) output when an object comes close to the sensor. This sensor only responds to 38 KHz modulated infrared light which makes it immune to disturbance caused by the ...
