Very well explained.
This is such interesting info
Thank you so much for the very detailed video!! :) I find it quite counter-intuitive that the digital pin is set to high when less infrared light is observed, would you happen to know why it is designed this way?
Great work sir, but it was malfunctioning under sunlight, please help with comprehensive details on how to overcome this challenge thank
Can the digital output of that little board be connected to an interrupt pin of Arduino Mega, so the arduino reacts instantly to the presence/absence of the reflective object?
Isn't the code displayed missing a couple of calls to analogRead(pinIRa) and digitalRead(pinIRd)? The serial output shows results that imply the calls are there.
Hi Sir..All you guidance is awesome.... you are really great ...lots of wishes..Sir i would like you to teach us for "Coin Separator" DIY if possible..
can i use this for a sensor to create a volume control/expression pedal?
Can we use this sensor to measure the glucose level in a solution?
Great vid. I'm trying to develop a product with this technology. Who would I talk to for consulting on building it? Thanks!
do you know of any sensor with similar characteristics but much smaller in size? thank you
I made a simple circuit with a regular white led and a photoresistor. It sucks at picking up changes in the daylight. Is this any better? If so, why? Is it a wavelength thing?
Is it okay to the TRCT 5000 IR SENSOR Module to ESP 32?
Hi. Many thanks for the good presentation.
You're welcome
is the analog output is distance in mm form ?
Great video, thanks. I have the TCRT5000 without the breakout board. Should I be including a resistor in my circuit?
Yes google the datasheet and check the max amp then use a resistor to bring current down if you have higher current
what does pinLED do?
Could I use tcrt5000 as analog input like potantiometer?
Can i connect ir sensor to arduino nano via wireless?
"Noise cancellation scripts", can you provide a debounce code for the TCRT5000, I recently made a modificated version of your coin sorting machine, but anytime a coin pass through the sensor, it starts to give me some extra noise data, and yes i have checked the potentiometer behind to adjust as low as I could.
@glyn hodges actually a last button state is a lot better than delay, so when it triggers once it stop counting infinite but only once! 😉
How can I use this to trigger a 555 timer ?
hey I did everything the upload went well the sensor is working but when I go to the monitor in series, only appear "???????" what should I do?
if ????? appears, then you need to change the Serial monitor rate. Open the Serial monitor and look at the bottom. Change your Serial monitor rate to 9600 then try again.
Can such a device, if pointed toward the ground, measure the reflectiveness of infrared light of objects inside the earth? If so, can you please tell me how to get my hands on a device with such capability?
so you want to detect IR (heat) from objects hidden in the ground?
@@bjornwegener3233 Yes, how can that be accomplished, any idea?
Hello, what about analog output? How does the signal is made? Is It a voltage +5 dropping down to 0 when an object Is near? Thank you 😊
The analog output will report back the intensity of the light measured at the sensor. The value will be between +5 and 0 (rarely at the extreme ends of the scale) As opposed to the digital output which would indicate a 1 or 0 depending on the reaching threshold set on the potentiometer.
@@DIYMachines that's perfect! I need to use it as a potentiometer and connect to a guitar pedal as a spare in a circuit which espects input value from +5 to 0V! Thank you :)
what is the measurement in? mm??
HELP HELP HELP
What am I doing wrong? Copied the code and get values from the serial monitor. However, when I slide a coin past it, it dosent sense it. I literally have to put my hand in front of it. I have tried with 3 different sensors and get the same result. Any help would be much appreciated. Im such a noob.
Keep calm! Try using a small screwdriver to adjust the potentiometer. This will adjust its sensitivity on the digital pin. Let me know how that goes.
@@DIYMachines Thank you so much for the reply, i have tried that but no luck? i am quite sure i must be doing something wrong, i have mocked up the £2 coin section in card and it is just not seeing the coin drop i have to drop the coin so slowly for any digital reading! any help or advice? very grateful
@@simonsmith7504 This is bizarre. Try reducing the size of the delays in the example code. Does this have any effect?
It can work in sunlight
Pls make a vedio on iron man helmet
Why does it needs to be conected to a analog input ?
it does not, the output of the sensor is analog, if you like use it, or if the digital suits your circuit better, use it, its nice they output both for different circuits.
Cant i use without arduino?
Yes you can. Use the LM393 and potentiometer on the sensor to set a trigger threshold.
Can it be used with a Raspberry pi?
Yes, absolutely.
Try using this on a black non reflective object. It will not register.
Yes you're correct. If the object is not very reflective then a sensor that employs a different method of detection would be more suitable.
Hi.....
Can this detect human beings presence. Guess not.
false experience
how?
so boring
What the total current consumption by this sensor?
