IoT-devices

What IoT-devices does

IoT-devices, LLC is a privately held Ukrainian electronics manufacturer incorporated in 2020 and headquartered in Kyiv (with some data indicating 2021 as the operating start). The company designs and manufactures a small, focused family of electronic modules for the DIY IoT and home-automation market. Its flagship product, the GGreg20_V3 ionizing radiation detector, pairs a Geiger-Muller tube (SBM-20 or J305) with a 400 V high-voltage bias and a GPIO pulse-counter output, exposing counts-per-minute (CPM), µSv/h, and cumulative µSv readings to a broad set of microcontrollers (ESP8266, ESP32, Arduino, Raspberry Pi Pico W, STM32, NodeMCU). Supporting modules include the DCDC_3V3_400V_V1 high-voltage DC-DC converter, the I2CUI4_V1 user-interface module (5-button keypad, RGB LED, buzzer), the I2CHUB_V1 I2C bus splitter, the GCemu20_V1 Geiger counter emulator (for development without radioactive sources), the ESP12.OLED_V1 ESP8266 controller board with OLED, the PS4IoT smart power module, and the GGreg20_ES epoxy souvenir variant. The ICL_RPIPW_ST_V1 plastic case (announced 2025) was developed jointly with IoT Case Lab.

The business model is product-led and B2C: hardware modules are sold primarily through the company's own Ukrainian-domiciled e-commerce storefront (iot-devices.com.ua/shop) priced in UAH (~$7 to ~$84 per unit), with an Etsy marketplace store (since 2023) as the secondary international channel after Tindie barred Ukrainian sellers. International orders ship from Kyiv via the Ukrposhta PRIME postal system covering 40+ countries; order processing is 4-7 days, with shipments going out only one to two times per week — a constraint consistent with a small operation. Customer segments are primarily individual DIY makers and IoT hobbyists, with a secondary use case in educational institutions, citizen-science projects (radmon.org, safecast.org, ThingSpeak), and hobbyist radiation monitoring. Distribution is amplified through a deep open-source software footprint — official inclusion in the Arduino IDE Library Manager, the Tasmota Supported Peripherals list, ESPHome contributor status, and a WOKWI simulator project — plus community engagement on GitHub, Hackaday, Reddit, Medium, Flipboard, Bluesky, and Facebook.

The company is bootstrapped (no disclosed funding rounds, no parent company, no external shareholders), operates with a 1-10 employee headcount, and continues to fulfill orders worldwide despite the ongoing war in Ukraine (most recent operating confirmation: June 2026). It has no AI/ML capabilities evidenced in its products, no patents or trademarks on record, and an empty management team roster in the available data — a profile consistent with a founder-led micro/niche business rather than an institutional venture. Notable accolades include inclusion in the Ukrainian Register of Best Suppliers of Goods and Services 2024, the Awesome Open Source Top 100 (2022), and Etsy Star Seller status for two consecutive months in 2024.

Core offering

IoT-devices designs, manufactures, and sells IoT electronic modules including ionizing radiation detectors (Geiger counter modules such as the GGreg20 family), high-voltage power supply modules, I2C user-interface and bus-splitter modules, ESP8266/ESP32-based microcontroller boards with OLED displays, smart power modules, and supporting enclosures. The modules are intended for DIY makers, hobbyists, and home-automation builders who integrate them into larger projects and pair them with third-party controllers.

Product overview

IoT-devices LLC is a Ukrainian electronics manufacturer (Kyiv) founded in 2020, producing a family of electronic modules for DIY IoT and home automation. The core product is the GGreg20_V3 ionizing radiation detector (Geiger counter) with Geiger-Müller tubes (SBM20, J305), which connects to popular microcontroller platforms (ESP8266/ESP32, Arduino, Raspberry Pi Pico W) via pulse counter output, integrating with ESPHome/Home Assistant, Tasmota, Arduino IDE, and NodeMCU. Supporting the GGreg20 ecosystem, the company offers the DCDC_3V3_400V_V1 high-voltage power supply module (200–1200V converter for Geiger tubes), the GCemu20_V1 hardware emulator for testing without radioactive sources, and the GGreg20_ES epoxy souvenir version. Additional products include the I2CUI4_V1 user interface module (I2C keypad, RGB LED, buzzer), the I2CHUB_V1 I2C bus splitter, the ESP12.OLED_V1 ESP8266 controller with OLED display, the PS4IoT smart power module, and the ICL_RPIPW_ST_V1 plastic case for Raspberry Pi Pico W.
