Description of 1 Channel 5V Relay Module
Quick Overview
The 1 Channel 5V Relay Module is a crucial element in circuit control, serving as an intermediary that allows for low-voltage systems to operate high-voltage devices. The module is widely utilized in robotics, home automation systems, and a myriad of other engineering applications where isolated control of electrical devices is required.
How It Works
A relay is essentially an electrically operated switch. Inside the module, you'll find an electromagnetic coil and a mechanical switch. When a low voltage (5V in this case) is applied to the coil, it creates a magnetic field that activates the switch, allowing current to flow through the high-voltage circuit. This design effectively isolates the low-voltage and high-voltage circuits, ensuring safety and reliability.
