Circuit Documentation

Summary

The circuit in question is designed to interface an MPU-6050 motion sensor, a LoRa communication module, and a water level sensor with an Arduino UNO microcontroller. The Arduino UNO serves as the central processing unit, reading sensor data from the MPU-6050 and the water level sensor, and communicating with external systems via the LoRa module. The circuit is powered through the Arduino's 5V output, which is distributed to the other components. Ground connections are also centralized through the Arduino.
