Gravity: Geiger Counter Module Ionizing Radiation Detector-1

Gravity: Geiger Counter Module Ionizing Radiation Detector

€56,55

The Gravity: Geiger Counter Module is a sensitive radiation detection module designed for educational use, physics demonstrations, and electronics integration. It comes pre-equipped with a M4011 Geiger tube, allowing it to detect ionizing radiation such as X-rays, gamma rays, and nuclear particles.

This module is ideal for makers, students, and engineers working on projects involving radioactive sources, natural radiation detection, or true random number generation.

Not for use in radiation dose measurement that directly affects personal safety.

 

What Can It Detect?

Radiation sources can be hidden in:

  • Marble and ceramic materials

  • Ores, minerals, and gemstones

  • Anion powders and decorative materials
    These can emit small amounts of natural radioactive elements, undetectable without a Geiger counter.

 

Features

  • High-sensitivity M4011 Geiger tube

  • ±400V drive voltage for reliable particle detection

  • Digital pulse signal output (easy to interface with Arduino, Raspberry Pi, and other MCUs)

  • Great for STEM learning, radiation science, and DIY physics experiments


Applications

  • Detecting ionizing radiation from natural and synthetic sources

  • Creating DIY nuclear monitoring devices

  • Teaching nuclear physics principles

  • Building entropy-based random number generators


Technical Specifications

Geiger Counter Module

  • Power Supply: 3.3V ~ 5V

  • Signal Output: Digital output (low when pulse detected)

  • Driving Voltage: Approx. 400V

  • Maximum Detection Range: 1200 µSv/h (theoretical)

  • Dimensions: 107 × 42mm (4.21” × 1.65”)

M4011 Geiger Tube

  • Operating Voltage: 380V ~ 450V

  • Background Counts: ~25 CPM

  • CPM Ratio: 153.8 CPM/(µSv/h)

  • Tube Size: Φ10mm × 88mm


Included in the Box

  • Gravity: Geiger Counter Module (w/ M4011 Tube) ×1

  • Gravity 3-Pin Sensor Connector ×1


Example Projects

Making a Desktop Geiger Counter with Unihiker --- Real-Time Nuclear Radiation Monitoring
Ionizing Radiation Detector

 

Important Notes

  • This product is designed for educational and demonstration purposes only.

  • It cannot be used for professional radiation safety evaluation or medical purposes.
