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.
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.

Emulator of radioactive particle detector is a hardware-software electronic module designed to emulate the counter of ionizing radiation level. For this purpose the emulator includes a pulse counting output to the main controller. Arduino, ESP8266, ESP32, Raspberry Pi, STM32 and others can be used as host controllers. GCemu20_V1 is based on ESP12.OLED_V1 hardware but with its own Geiger counter emulator software application.
The simulated radiation level and operation mode of the emulator are indicated by light signals on the built-in RGB-LED.

I2CUI4_V1 - user interface I2C keypad with 5-keys, RGB LED and buzzer powered by MCP23017 IO Extender
I2CUI4_V1 module – user Interface I2C keypad with 5-keys, RGB-LED and buzzer for on premise IoT device management. Based on MCP23017 IO Extender and compatible with Arduino, ESP12.OLED_V1 controllers, NodeMCU board (based on ESP8266-12), modules on the ESP8266EX, ESP32, Raspberry Pi series or other chip, which is powered by a voltage in the range from 1.8 to 5.5 V. Driver support: NodeMCU, Tasmota, ESPHome, Arduino, OpenHab, Blynk, NodeRed, Home Assistant.
The module connects to the main controller via a 4-wire I2C bus interface and provides the following functions: Data entry with a five-button keyboard (left, right, down, up, OK); Data output to RGB LED; Output of sound sequences to the active indicator of the buzzer type; I2C bus input and output through ports. Input for connection to MCU and output – for connection of any external devices that support the I2C specification.

The I2CHUB interface splitter module is a passive device and allows you to connect several (up to five) devices (sensors or actuators) to the main controller at the same time. The controller and splitter form a network of connected I2C devices with a bus-type topology and Master-Slave interaction profile.
Also, if you install different connectors (JST and/or Dupont) on the board of the splitter module, I2CHUB will also act as a converter of physical interfaces, which is very convenient for prototyping and development.
Multiple I2CHUB devices can be freely cascaded within the limits allowed by the I2C bus specification, and further, expand the total number of free ports in the network of subordinate smart devices of the master controller.

GGreg20_ES (souvenir Geiger counter) is an unusual artistic product: on the one hand, it is a built-in DIY electronics, on the other hand, it is a product that is not intended to work. The coating is a transparent, non-toxic epoxy resin EpoxyTable 5-five from RESIN PRO (Italy) with powerful UV filters. If you decide to order such a souvenir, you will participate in two charitable initiatives with the IoT-devices team.
No cabling – No soldering – No drivers – No coding
