Brain - puzzle game - set for self-assembly

Versatile ESP32 module with LoRa and Wi-Fi support, designed for monitoring people flow and creating mesh networks in difficult conditions, such as in areas cut off from the network. The device can detect Wi-Fi and Bluetooth signals, allowing estimation of the number of mobile devices in the environment without recording MAC addresses, which protects privacy. The module offers low power consumption, data storage on SD card and data transfer via LoRa WAN or MQTT, making it a reliable and self-sufficient solution for emergency communication. modTTGO LoRa32 v2.1

A portable combustible gas detector designed to detect methane, propane, and isobutane. The device features a 2.0" color TFT screen, three alarm modes (audible, visual, and vibrating), and a flexible 36 cm probe for easy access to hard-to-reach areas. A response time of less than 5 seconds and the ability to record up to 30 alarm events ensure fast and precise threat detection. Fnirsi GD-02

2-channel remote control receiver - set for self-assembly

AVR, 2kB Flash, 128B RAM, 128B EEPROM, DIP20, RoHS

A multifunctional electromagnetic radiation detector that measures electric fields, magnetic fields, RF radiation power, and ambient temperature. Equipped with a 2.4-inch color screen and data hold function, it provides clear readings and intuitive operation. It allows you to set alarm thresholds, supports automatic shutdown, and offers firmware updates and factory resets. Thanks to a 1000 mAh battery and USB-C charging, the Fnirsi ERD-10 is portable and convenient for everyday use.
