GSM-based smart relay is a device that allows users to remotely control the on/off state of an electrical appliance or device by making a phone call to the relay’s dedicated mobile number. When the relay receives a call, it automatically answers the call, recognizes the caller’s number, and activates or deactivates the connected appliance accordingly. This technology offers a convenient and efficient way to manage devices from a distance, making it ideal for home automation, security systems, and various industrial applications. Users can remotely control lights, heaters, air conditioners, pumps, and other electronic devices, enhancing control and energy efficiency.The GSM controlled relay module project centers around crafting a solution that allows you to remotely control devices with the help of a mobile phone. By combining the power of GSM technology with relay modules, you can create a flexible and efficient system with endless applications.

Key Components of the GSM Controlled Relay Module Project:

  1. Relay Modules: These act as the switch that controls the power supply to devices. By integrating relay modules, you can remotely turn devices on or off.
  2. GSM Module: The heart of the project, the GSM module enables communication between your mobile phone and the relay modules. It receives commands via SMS or mobile app and translates them into actions.
  3. Microcontroller: A microcontroller, such as Arduino or Raspberry Pi, serves as the brain of the project. It processes commands from the GSM module and triggers the relay modules accordingly.
  4. Power Supply: Reliable power sources ensure uninterrupted operation of the system.
