  • Gravity Geiger Counter Module Ionizing Radiation Detector
  • Offers large-scale and highly sensitive Geiger tube
  • Detect ionizing radiation
  • Provides a good random number generator
  • Easy to install layout
  • Power Supply: 3.3 ~ 5 V

The Gravity Geiger Counter Module Ionizing Radiation Detector detects ionizing radiation, such as nuclear radiation, X-rays, cosmic rays, etc. Electromagnetic radiation such as microwave oven radiation, mobile phone radiation, WiFi radiation, and induction cooker radiation can not be detected.

In addition, the Geiger counter is a good random number generator, and undetermined high-energy particle ionization events can provide enough random entropy to get you a truly random number, rather than a fixed random sequence based on a random algorithm.
