Adafruit Geiger Counter Kit - Radiation Sensor

Detect particles and make a cool random number generator with this hands-on Geiger counter kit. This easy-to-assemble set transforms a Geiger-Muller tube (included) into a portable, blinking, beeping radiation detector.

Connect an FTDI friend to the header for serial output and datalogging on your computer. With just a few hours and basic soldering tools, you'll have a functioning device perfect for exploring radiation sources, from granite countertops to vintage glow-in-the-dark clocks, old FiestaWare, and chunks of Uranium.

All components—PCB, tube, and parts—are included; just supply two AAA batteries. Remember, this Geiger Counter kit is for educational purposes only. It is not suitable for monitoring radiation in hazardous environments or life-threatening situations. Always prioritize safety and do not depend on this kit for precise radiation measurements.
