How to build an IR Sensor » maxEmbedded

An IR sensor is basically a device which consists of a pair of an IR LED and a photodiode which are collectively called a photo-coupler or an opto-coupler. The IR LED emits IR radiation, reception and/or intensity of reception of which by the photodiode dictates the output of the sensor. Now, there are so many ways by which the radiation may or may not be able to reach the photodiode. Let’s ...

Basics of IR Sensor | IR LED Pin Diagram & Working

· IR sensors find a wide variety of applications in various fields. Let’s take a look at few of them. Proximity Sensors . Proximity sensors employ reflective indirect incidence principle. The photodiode receives the radiation emitted by the IR LED once reflected back by the object. Closer the object, higher will be the intensity of the incident radiation on the photodiode. This intensity is ...

IR Led and IR photodiode question - Sensors - Arduino Forum

· Sensors. system November 12, 2014, 3:19pm #1. Hey all, Looking for some confirmation about an IR Led and photodiode (two pin). used for object detection. This is the LED Since forward voltage drop is V, and assuming I'm using a 5 V source from the Arduino, I assume I need to find a resistor. So which current would I use when finding this resistor, would it be the forward current of 150 …
