Sensor IR y LED

: infrared sensor light

Jul 29, 2019· Active IR sensors have two parts: a light emitting diode (LED) and a receiver. When an object comes close to the sensor, the infrared light from the LED reflects off of the object and is detected by the receiver. Active IR sensors act as proximity sensors, and they are commonly used in obstacle detection systems (such as in robots).

Arduino and IR LED based Proximity Sensor

Dec 11, 2020· The IR LED is connected in forward bias in the sensor module. As 5V DC powers the module, the IR LED starts emitting IR radiations. An IR photodiode is placed parallel to the IR LED to detect the reflected radiations. The photodiode is connected in a voltage divider network, whose output goes to the inverting input of LM393 comparator IC.
