Summary of the Circuit

This circuit integrates an Arduino Nano microcontroller with a Sim800l GSM module and an SW-420 Vibration Sensor. The Arduino Nano serves as the central processing unit, controlling the GSM module for cellular communication and monitoring the vibration sensor for any physical disturbances. The Sim800l GSM module enables the circuit to communicate over cellular networks, while the SW-420 Vibration Sensor detects vibrations and sends a digital signal to the Arduino Nano.
