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. 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.

Geiger counters are used to detect radioactive emissions, most commonly beta particles and gamma rays. The counter consists of a tube filled with an inert gas that becomes conductive of electricity when it is impacted by a high-energy particle.

This is a timelapse of the assembly process of the geiger counter.

Connect P3 GND, 5V, VIN to Arduino GND, 5V, Digital 2 respectively.

Then in the arduino IDE software open the file: spi_rad_logger.ino which you could find

Be sure to change the Serial.print(cpm) command to Serial.println(cpm) in the void loop(){} for better readability.

Upload the program onto the board. Once upload is completed, open the serial port window by clicking on the scope on the upper right corner.

Then we’ll get the radiation value displayed in CPM, counter per minutes which could be converted to uSv/h with the index 151(151CPM=1uSv/h for M4011 GM Tube).
