Description
A Relay Module is an electrically operated switch that allows low-power circuits to control high-voltage devices, commonly used in automation and IoT projects. In cybersecurity, relay modules can be employed for simulating power control systems in physical security environments, testing vulnerabilities in smart grids, or executing physical attacks such as turning on/off devices remotely. Beyond security, they are widely used in home automation, robotics, and industrial control systems to manage electrical appliances, lighting, and motors from microcontrollers like the Arduino or NodeMCU.
