The GGreg20_V3 radioactive particle detector is an electronic sensor module for building a personal Geiger counter and determining the level of ionizing radiation. For this purpose, the detector includes an impulse counting output to a host controller. Arduino, Raspberry Pi, ESP8266, ESP32 and others can be used as a host controller.

The radiation level is indicated by light and sound signals. The user can mute sounds (jumper J1 – buzzer on/off).

GGreg20_V3 is an inexpensive and useful device for checking the “purity” of

• mushrooms,
• berries,
• vegetables,
• firewood, etc.

This module is useful for creating smart measurement devices for determining the power of ionizing radiation indoors or outdoors and is available in both portable/pocket style and stationary mode.

The only thing you need to start measuring ionizing radiation with the GGreg20 is any microcontroller that can count the number of pulses per unit time on GPIO.
