Nice to see these on little module boards. I use an old laser pointer and a phototransistor on my chicken coop to keep the automatic door from squashing my birds.
I have these lasers setup for a basketball arcade game. They work great but if a ball hits the basket. It registers a score. Any ideas to make these less sensitive?
Hi, the problem with this setup is that when the laser is interrupted the input in the arduino is left floating, which means that you don't get a deterministic low signal.
Yes very easily. First learn how to use the the “if” statement to take action. Perhaps learn it from this video ESP32 Project 24 - Measuring Soil Mositure for Irrigation | SunFounder's ESP32 IoT Learnig kit ruclips.net/video/MW-7a5Z0IT0/видео.html and the learn how to use the a relay. I have tones of videos on relays. Search my channel.
hello my laser isnt working and i dont know why could anyone help me i followed the tutorial exactly it just blinks a couple of times then stops idk how to fix it
I have purchase the KY-008 laser with the associated sensor board. For my project I only need the 3 pin sensor but I'm unable to identify it, and I can't seem to find any references to it on all the sites that are selling it. Does anyone know the Mfr and Part Number of the detector which inserts into the 3 pin socket? Thanks!!!
@@robojax You mis-understand. I'm looking for the part number of the receiver only. Just the detector that has the tiny lens bump on it. I want to purchase it separately without the board that it mounts on.
it is already cheap. just get the with the bord and discard the boad. when I was making this video, I tried to find so I could includ it in the video and even today I tried but could not find it.

Interesting application.
great effort worthy of admiration...thank you
sunlight affect?
Great video
Would you be able make a touch screen screen frame/overlay using this method.

👍
Does the laser need to be completely obstructed to trigger the sensor? Could a 0.05mm copper wire be detected?
that is tough to know. I have not tested. Let's see if anyone else has done it. Try it.
@@robojax Yes. I might have to try.
Hi I can't find iso203 sensor, can I use pd438c sensor? how can I?
Nice ahmd
Hey would it be possible to use this system to tell 2 6V DC motors to rotate whenever the signal is interrupted?

Dumb question but is the buzzer passive or active. I want to buy it but I don't know which one to pick. Can you tell me about that? Please
Not question is dumb question. This called active buzzer.
What is the maximum distance between the transmitter and the receiver?
as for as you can see and aim it. there is no limit. with naked eyes, you can't see the receiver to aim in a distance longer than 10 meters.

try interchanging the polarity. In my case I had the S and - mis-written on the PCB. I just inverted my connections, it worked..

you can identify it by watching the video. it is veyr simple. it is + and GND and output and I have shown it.

Hi what's the name of the laser detector please
Hi, you just answer it. I t is receiver or detector and I just added the purchase link I the description below the video.
@@robojax yh like i mean the laser’s name is KY-008 but you didnt mention the name of the detection
that is the name "detector" or "sensor" it has no model or anything. Just follow the links you will see it
