Find this and other hardware projects on Hackster.io. About: Ngo active in the field of digital mediation, based in Toulouse, France hopefully my build goes well and i can help others.

The counter comes with an analog gauge, a rotary selector to select modes and a control knob to adjust the zero offset. 11 months ago

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.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. DIY Arduino Geiger Counter: Hello everybody! I connect display to the detachable cable, insulate it carefully, it's very near to the high voltage module. All parts in the project are through-hole easy to solder. I'm sorry sir. With that said, you need a simple BJT switch to protect the Arduino. How do you do?

Geiger counters are used to detect radioactive emissions, most commonly beta particles and gamma rays. Hello, Great Project. 8 weeks ago But I'm still little bit confused about how the common emitter BJT transistor works on this circuit as a switch. For that purpose, the pulse from the tube is applied on the base of the BJT allowing Collector/Emitter current. 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.

Can you explain me, why it's use common base BJT on this project?

If collector-emitter shorted out then I get +1 on screen. 5 months ago

Reply Geiger Counter With Arduino Uno: In this tutorial you will learn how to assemble and use a nuclear radiation detector.You can purchase the Geiger Counter Kit here.A Geiger counter is an instrument used for detecting and measuring ionizing radiation. 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. 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. Thanks for watching, see u next time!Tip 1: Since the Interrupt attached to D2 is waiting for a falling edge of the signal, there is a missing INTERNAL_PULLUP on D2. Answer But you need to adjust the high voltage with the 10MOhm resistance ! What happens to that voltage after passing the transistor sir?

Some hot glue. 5 months ago In this tutorial you will learn how to assemble and use a nuclear radiation detector.A Geiger counter is an instrument used for detecting and measuring ionizing radiation. The tube works. 8 weeks ago If i want to make Geiger counter that just count of alpha radiation or make radon detector, what should i do or modification from this project? Many thanks! I just want make this project for my project school, can you help me please? I made it, but doesn't work. 3 months ago 2.00 RH-K-GK-2-A with UART logging. 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.Lets move to the practice, for the brain I choose arduino nano, 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. The voltage used to power the Geiger-Muller tube in this particular circuit is 400 volts. hello can you tell me what is the purpose of the resistance 10 M at the output of the high voltage step up DC-DC. Reply Hello, i successful connect Arduino with display and get data from Geiger with software (Radiation Logger). 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.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. When there is Radiation itu will produce a voltage 3.9volt. With it only the pulses from the sensors actual trigger the interrupt. What could be the problem? 7 months ago i also recently found another one gieger counter build on here that features a touch screen, so maybe worth checking out. Thank you. This is project How-ToDo my name is Konstantin, and today I want to show you how i made this Geiger counter. 8 weeks ago You can use EasyEDA free software to draw the schematic. 8 weeks ago Reply Also known as a Geiger–Mueller counter (or Geiger–Müller counter), it is widely used in applications such as radiation dosimetry, radiological protection, experimental physics, and the nuclear industry.
