From the project

hardware system based on ESP32-C3 (RISC-V architecture) on a 4-layer PCB for noise immunity. The project includes sensors (environment, light, and sound), smart power and charging management (MCP73871), and a user interface. system supports local data storage via SD card and external flash memory via SPI connection, with Wi-Fi and BLE connectivity.

A battery-powered, 4-layer IoT sensor hub built on the RISC-V ESP32-C3. It measures temperature, humidity, pressure, light, and sound, logs to microSD and SPI flash, and connects over Wi-Fi and BLE.

- All-in-one sensing: a BME280 (temperature / humidity / pressure), a TEMT6000 ambient-light sensor, and an electret microphone with a MAX4466 amplifier. - Local data logging: a microSD card slot plus 32 Mbit W25Q32 SPI flash. - Wireless: an ESP32-C3-WROOM-02 module (Wi-Fi + BLE 5) with the antenna placed at the board edge. - Power-path management: the MCP73871 charges a 1S LiPo while powering…
