PiGI - A Raspberry Pi Geiger-Mueller Interface

Image

The PiGI is built as a ready-to-go drop-in module for the Raspberry Pi to transform it into a versatile geiger counter to measure/monitor radioactivity. It will generate the required high voltage the counting tubes need to operate and it will safely invert the counting impulses to a falling edge, detectable by a GPIO Pin on the PI. But it's also designed in such a universal way in order to be very hackable. Basically it can be connected to any processing system that can detect falling edges like:

  • Arduino
  • ATMega
  • PIC
  • Other embedded Linux ARM/MIPS systems with GPIO Inputs (GNUBLIN, Netus G20 etc.)

Specifications

  • 40x43mm board
  • Very low energy consumption (<2mA @ 0.09uSv/h local dose rate)
  • Cathode counting
  • Low BOM count / small footprint
  • Very cheap design: Prototype costs per board -> EUR15 / High Volume Production < 10 EUR
  • Dual stackable for low/high dosis counting with 2 tubes
  • Open-Source Hardware/Software

Hardware

  • Schematics
  • Board designs
  • Released under CERN OHL 1.2
