Circuit Documentation

Summary

This circuit integrates various components to perform a set of functions centered around the ESP32-S3 microcontroller. The circuit includes sensors, a display, power management modules, and user interface elements. The ESP32-S3 serves as the central processing unit, interfacing with an ADXL355 accelerometer, an SW-420 vibration sensor, an ILI9341 TFT display, and a buzzer module. Power is managed through a 12V to 5V step-down converter and a UPS for uninterrupted power supply. User inputs are captured via a push switch and a rocker switch.
