Thank you for liking my video and helping me to 10,000 subscriptions today! Although the original site has been taken down, by the magic of the inteweb the project can be viewed in part by means of the "way back machine" : web.archive.org/web/20131006065447/www.cooking-hacks.com/documentation/tutorials/geiger-counter-arduino-radiation-sensor-board Thanks for watching, have a great day!
Hi, as far as I can remember (it was 7 years ago!) the delay is to allow sufficient particle counts to accumulate. Hopefully you should be in a place where the radiation levels are not that high and so if a shorter delay was used it is possible no counts would register. I think this then results in the values being more representative of the amount of radiation present. Feel free to experiment with this value. Thanks for watching, have a great day!
Nice, thank you. The uSv/h reading arguably has too many digits. When the CPM is "30", then the uSv/h is "0.2436" which is overly precise considering that the input data is just 30. It's a "Significant Figures" detail.
Gave this project a build but with a I2C OLED display. Looks nice, but its a smaller than the LCD so a more difficult read. So now once I move it to a nano and then 3d print a case, it should be good to go. Any idea how to calibrate the geiger board? I have access to a radiation meter (as im a radiation worker) so getting accurate numbers is easy for me. However this geiger kit has surprisingly little data online. I'm guessing the trim pot on the board is for calibrating the count rate?
DO NOT TOUCH THE TRIM POT!! It sets the high voltage for the Geiger tube!

@@1nformatica thank you for the advice and the response on an old video. I definitely won't be touching the trim pot, lol. Once I've completed the build (3d printed case and all), I will send you some pics of it if you'd like.
Lovely informative video's hope to see that follow-up. I've bought the same module and am therefore quite curious how it holds up compared to a calibrated one.
Thanks! I have compared it to a Gamma Scout costing around €400 and it was in general agreement. You can see the Gamma scout on this link: www.gamma-scout.com/EN/Leistungsmerkmale.php I had some problems with my camera doing the video but hope to salvage what I can and upload it soon.
There is a position on the board for a jumper to enable the audio jack marked P100 you can see it on the left above the jack socket in my first video: th-cam.com/video/4Tqo3B98ZgM/w-d-xo.html
I would try loading one of the Arduino test sketches for the LCD. Having got that working it should be easier to go back to the project and find the issue. Good luck!
@@1nformatica I think I need to look into the 555 circuit a bit. I got the output on the LCD, but if it sees anything over ambient radiation it will eventually throw bad characters on the LCD.
That is a great idea! You could use an M5Stack module which has an SD card slot and also a GPS module. bit.ly/M5StackGPS M5Stack Core ESP32 bit.ly/M5Stack th-cam.com/video/po3pbBcOxzA/w-d-xo.html

I went to the location where the B52 crash was and when filming was approached and "advised" not to continue. The unit works well and I checked it against a professional Gamma Scout meter and they were in agreement.
@@1nformatica I bought Arduino kit and ordered the same counter. I am gonna build this geiger counter project. But prob will be in outside of the counter. Final product will look like a mine detector. I will use it to hunt uranium ore.
@@1nformatica it's done. I didn't use that circuit with 555 IC. I changed code ''attachInterrupt(digitalPinToInterrupt(2), countPulse, RISING);'' into attachInterrupt(digitalPinToInterrupt(2), countPulse, FALLING); and it works!! I connected VIN pin on geiger to pin-2 on the arduino.
Could you help me ( arduino uno remote connection and codes)? I want to take this measurement from far distance. I also need these codes at the same time.
Hi, recently I have done some projects using "LoRa" modules to send data (temperature readings) to remote Receivers. That may give you some ideas : th-cam.com/video/2Q4O88hmjzE/w-d-xo.html Also see : th-cam.com/video/etzn2lIEOX4/w-d-xo.html

The glass beads only contain a miniscule amount of Uranium oxide ay 0.2%. I cannot see that being a problem. When I was at school and my physics teacher was demonstrating radiation with some samples (lead apron and everything) he asked if anyone had a watch with a luminous dial. My friend had his father's watch from his time in the air force. When tested the counter went off the scale!! Way more dangerous than the samples!
@@1nformatica incredible! What a Dangerous Watch... That was Just uranium, not oxide! 🧐 Or simple Just tritium that Is a lot used It that field, but Is not this Dangerous beacause Is still legal.
5 years later and you helped me big time with my electronics project involving the same radiation sensor - Thanks!
You're welcome! Have a great day!!

Excellent job. More relevant than ever these days.
Thanks! I enjoyed researching my family history and the local area where I now live.
Fantastic job, man! Really, really nice project!
Obrigado Mario! Trying out for real will be interesting, I have my "nuke suit" ready!!
1nformatica Great! :D Love those kinds of things. LOL
1nformatica brilliant project 👍👍👍
Thanks! Can't wait to go out in the field with it. I expect I'll get some funny looks but what's new!!
what would happen if you remove the 3 second delay at the end of the code ?

The box remembers me of the old tricorder, from the original series. :D

Did you find out what these 2 pins described as P100 are for? Maybe they give cleaner signal than VIN?

I've almost got it all together! It looks good on the Serial Monitor, but having issues debugging the LCD interface.

It seems like you have noise on the signal. If you have an oscilloscope you should see a clean pulse.
For field job one may also add GPS logging and ah yes sdcard logger
That is a great idea! You could use an M5Stack module which has an SD card slot and also a GPS module. bit.ly/M5StackGPS

Build a Simple ION Chamber to detect the Apha Particles. You could mount your Geiger Tube in a wand connected to the PCB via some Coaxial Cable.
one thing though, do you need a window on the box for better sensitivity or how do you calibrate for pvc enclosure for beta and gamma?

There _must_ be something wrong with the conversion, because: 120 CPM equals ~ 0,0001 mSv /h
The calculation from CPM to mSv/h includes a conversion factor depending on the tube characteristics th-cam.com/video/CPW7CREKkEo/w-d-xo.html
