A tutorial on How to make an InfraRed (IR) proximity sensor circuit along with detailed explanation on how the circuit works. The sensitivity or Range of detection can be controlled by adjusting the potentiometer.
This circuit can also function as an InfraRed receiver and Object detector.
For circuit diagram plus more Info, visit:
elonics.org/infrared-ir-proxi...
Components Required:
* LM 358 IC
* 1 InfraRed LED PhotoDiode pair
* Resistors: 2 x 270R, 10K
* Potentiometer: 10K
* Breadboard
* Power Supply: (3-12)V
* Few Breadboard connectors
Note: For supply voltage of 9V or more, use 1K resistor for LED and 470R for InfraRed(IR) LED.
This channel has a lot more electronics projects & 555 timer projects. So feel free to check them.
-----------------------------------------------------------------------
Troubleshooting Guide:
[Update]: • Troubleshooting IR Pro...
* Double-check all connections by referring to the circuit diagram.
* Check if the LED's are working properly. (Digital cameras can detect InfraRed light, so you can check if the InfraRed LED is working by using any digital camera)
* The IR photo-diode used in this video is white and the IR LED is black. But it can also be the other way in your case. You can determine which one is LED/Photo-diode by connecting both the diode, photo-diode pair separately to the power supply (via a 220 resistor) and see which one glows using a digital camera.
*At one extreme position of the potentiometer's knob, the LED should be off and at the other extreme position, the LED should be on. Now you can start turning the potentiometer's knob form the extreme position where the LED is on, until the LED just turns off. Now the IR proximity sensor should work properly.
*If the above steps doesn't help, feel free to post the problem in the comments section.

@Stoneman06660 5 лет назад

Great video, mate. This is the setup I had in my head but wasn't sure how it'd work, and you've gone through it in a clear and concise manner. We even have two channels on the op amp, so we can build a dual sensor unit in this manner that doesn't require an Arduino or what not to act at the comparitor or voltage reference-measurement. Love it.

@jbumstead21 6 лет назад

Thanks for posting this tutorial. This circuit worked for me. Although my IR receiver is black and my IR emitter is clear, which is flipped from what is shown in the tutorial. I had to adjust the 10kohm resistor to change the sensitivity for my application.

Great video, very well presented. For some reason mine was on and turning off with proximity. After much consternation I swapped the wiper (center tap) of the pot and put it on #3 and moved the receiver wire to #2 and lo and behold it worked. Not sure if the schematic is wrong, my LM358 is backwards or something else. Note, if I approach the circuit from one side it has a range of approx. 3 feet.

@claytonbenignus4688 4 года назад

My review of this is from the viewpoint of a beginning hobbyist. My review is generally positive. On the plus side, you discuss how it works and how to put it together. This is a big plus. On the minus side, you do not show a schematic, which is mitigated by the link to it. Also, you did not go into detail about each pin of the LM358, although this could be mitigated by a reference to a video covering the subject. You get substantial extra credit for that link to the troubleshooting video. This is Gold to a beginner. I’m subscribing because I see tons of potential in you. You do not make annoying presentation mistakes like using messy low contrast schematics on ruled paper, the type of mistake that gives the audience eye strain. Your script is well crafted and probably rehearsed. I am expecting great things of you.

@elonics 4 года назад

Thank you for the comprehensive feedback! I liked the idea of having reference videos. Will do that for the upcoming videos.

@claytonbenignus4688 4 года назад

One more caveat: References are good, but do not over do them as DC Comics did. They had successful series in the 60s called Crisis on Earth One, Earth Two, etc. Afterward, each issue of DC had increasingly many Editors Notes until the whole thing became a monstrous unreadable mess in the 80s. DC had to redo everything because no one could read through their tangle. References are good, but don’t be tedious.

@idreesquadri3641 4 года назад

Your circuit has a humongous flaw that will render this useless. You've labelled your photodiode as a transmitter, And you've labelled your infrared diode as a reciever. The entire circuit and theory behind this is perfect, but you have to swap these two. Infrared diode(transparent) positive pin to VCC, negative to R1 resistor which is then grounded. Photodiode(black) positive pin connected to pin3 of OpAmp as well as a resistor which is then grounded. Negative pin of photodiode to positive.

@WhoWantsToKnow81 6 лет назад

If you are all are wondering why the LED is continuously on, it is because there is no barrier between the light detector (white) and IR LED (blue), so it will always pick up light... Some masking tape between the two - without covering the domes - should help (although I have not tested this circuit myself).

@tarunkumargoel6737 4 года назад

Sir, Your explanations are really very good !👌🏼 Could you please explain the same IR Sensor circuit when using an LM567 IC. The LM567 is to be used as it allows usage of IR Sensor even in bright Sunlight. Thanks in advance, Sir.
