Introduction: DIY Arduino Geiger Counter

By My YouTube channel
About: Just do things, electronics, woodwork, etc.

Hello everybody! How do you do? This is project How-ToDo my name is Konstantin, and today I want to show you how i made this Geiger counter. I started to build this device almost from the beginning of last year. Since then it has gone through 3 complete rework and my laziness. The idea to make a dosimeter appeared from the very beginning of my passion of electronics, the topic of radiation was always interesting to me.

Step 1: Theory

So actually dosimeter is very simple device, we need the sensing element, in our case - the Geiger tube, power for it, usually it is about 400V DC and an indicator, in the simplest way is just a speaker. When ionizing radiation striking the wall of Geiger counter and knocked out electrons from it, it makes the gas in the tube conductive, so power goes directly to the speaker and it clicks, you can much better explanation on the web if interested. I think everyone will agree that clicks are not the most informative indicator, although it will be able to warn about the increasing radiation, but counting them with a stopwatch for an accurate results is kind of weird, so I decided to add display some brains.

Step 2: Design

Lets move to the practice, for the brain I choose arduino nano, program is very simple it's counting pulse of the tube for a certain time and display it on LCD, also it's show nice radiation warning sing and battery level. As a power source I use 18650 battery, but arduino needs 5v, so I DC-DC bust converter and li-ion charger to make devise completely autonomous.

Step 3: High Voltage DC-DC

I have hard time working on a high voltage power supply, originally I build it by myself, wound a transformer about 600 turns in secondary coil , drive it with MOSFET transistor and PWM from arduino. It's working, but I want to keep things simple, it's better when u can just buy 5 modules, solder 10 wires and get working devise then winding a coil, adjusting PWM, I want anyone to be able to repeat it. So I found high voltage DC-DC bust converter, it's strange but it's hard to find and most popular module has about 100 sales. I ordered it, made a new case, but when start to test - it gives out a maximum of 300V but the description says up to 620v, I tried to fix it, but the problem probably was in transformer. Whatever, I bought another module and it came in different size description says the same... I returned money but keep this module because it gives 400v we need, but anyway maximum 450 instead 1200 (something is really wrong with Chinese measuring devises... ) I made a new case, again.

Step 4: Components

And so in the end we have a design almost entirely consisting of modules:

Battery, optional active piezo buzzer and Geiger counter itself, I'm using old made in USSR tube, called STS-5 it's pretty cheap and easy to find on ebay or amazon, also it's going to work with a SBM-20 tube or any other, you just need to write parameters to a program, in my case the value of micro-roentgen per hour is equal to the number of tube pulse in 60 second. And well, the case printed on a 3d printer .

Also there are pretty cheap Geiger Counter Kits u might be interested. ( Aliexpress OR Amazon )

Step 5: Assembly

Lets start an assembly, the first thing to do is to set the voltage on the high voltage DC-DC with this potentiometer, for STS-5 it is approximately 410V. Then simply solder all the modules together by this circuit, I use solid wires, it will increase stability of construction and it is possible to assemble the device on the table, and then just insert it into the case. An important point, we need to connect in and out minus of the high voltage converter, I simply solder a jumper. Since we can't just connect an arduino to the 400v, we need a simple transistor circuit, I make it point-to-point wiring and wrapped it in a heat shrink tube, a 10MΩ resistor from + 400V was fixed right into the connector. It's better to make a cupper foil bracket for the tube, but I just twist a wire around, it's working fine, don't reverse plus and minus of Geiger counter. I connect display to the detachable cable, insulate it carefully, it's very near to the high voltage module. Some hot glue. And assembly is done!

Step 6: Final

Put it in the case and we are to test it. But I don't anything for tests, by the way Background radiation is looks fine. What can I say, is this devise working? Yes, sure. But I see a lots of way to upgrade it, for example large display so u can draw graphics, Bluetooth module, or use Sievert instead of Roentgen. I'm okay with device, but if u will upgrade it, please share! So thats all I got for today, hope u like it, and if u do please share this video in social media, it's really helps. Thanks for watching, see u next time!

Hi, does anyone have a program for a large display 1.3" 128x64 OLED display I2C for which there is a 3D box from Thingiverse?

Hi astalalavista, I made my own code based off the doz.ino code below in the comments. Im using an Adafruit 1.3" 128x64 OLED display I2C and its working fine, until I plug in the 400v dc-dc boost converter... Im using some different parts, for example, the tube is an SBT-9, which has an alpha window, im also using the more modern Arduino Nano RP2040 connect and two high value resistors for a voltage dividor to measure the battery voltage.
There is also a button to cycle between microSieverts, Counts Per Minute and Total Counts. My code is made with the SBT-9 in mind, so if you use another tube, you'll have to change the values in void "microSieverts_Hr()" function to get accurate readings.

Hi,
Thank you very much for your reply. I will try your edit in the future. I managed to modify the program from Moritz v. Sivers PKE meter Geiger counter.

Hi! Thank you for making your wonderful idea open source! I was thinking instead of using a HV module with a geiger-muller tube, using a bpw34 photodiode with a preamp for the signal. Possibly a simple mono audio amplifier. What do you think?
Thank you

Question: is your dosage rate in miliR or microR? it makes a very large difference in exposure over time as well as how acute your counter is registering! :) TY in advance for the info!

Hello, Great project, I made one and it works fine! But you need to adjust the high voltage with the 10MOhm resistance ! Many thanks!

Hi! do you mean to adjust voltage to 400 V between the geiger poles once you've connected the 10M resistance??
Thank u!
