The GSM-Based Appliance Control project allows users to remotely control home and industrial appliances using SMS commands. A GSM module connected to a microcontroller receives text messages from the user and switches appliances ON or OFF accordingly.

This system is very useful for home automation, industrial equipment management, and agricultural applications, especially in remote areas where internet access is not available.

Parts Used:

1. Microcontroller (Arduino / PIC / ESP32) – Processes commands
2. GSM Module (SIM800L / SIM900A) – Receives SMS from user
3. Relay Module – Switches appliances ON/OFF
4. Appliances (Fan, Light, Motor, etc.) – Load devices to be controlled
5. LCD / OLED Display – Shows status of appliances
6. SIM Card (Any GSM network) – For communication
7. Power Supply (Battery/Adapter) – Runs the system
