Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes various sensors, a microcontroller, and power management components. The circuit is designed to interface with multiple sensors and modules, including a load sensor, IR sensor, accelerometer, GPS module, and a distance sensor. The ESP8266 microcontroller is used to process data from these sensors and communicate with other devices. Power is managed using a 18650 battery holder and a TP4056 charging module.
