IoT Geiger Counter with ESP32, OLED Display, Thingspeak Channel and MQTT

A nuclear radiation sensor with a Geiger–Müller (GM) tube as the detector. This widely used solution is cost-effective, easy to construct, and ideal for measuring ionizing radiation.

Nuclear radiation sensor with ionization chamber as a detector. Hard to make, IMHO inferior to semiconductor detectors.

IoT for Radioactivity Monitoring (HW+FW)

Measuring radioactivity level by using RaspberryPi camera. Currently doesn't work.
