Gravity: Digital 5A Relay Module for Arduino
Simple, Reliable Switching for High-Power Devices.The Gravity: Digital Relay Module provides safe and stable ON/OFF control for high-power AC and DC loads through a standard low-voltage digital signal. It is widely used in automation systems, Arduino-based projects, smart home devices, and industrial prototypes.
Designed for plug-and-play integration, the module eliminates the need for external driver circuits while offering clear status feedback through a built-in indicator LED.
Features of Gravity: Digital Relay Module
Operating Principle
The relay functions as an electrically controlled mechanical switch. A low-power digital signal activates an internal electromagnetic coil, which mechanically opens or closes the high-power circuit.
Switching is suitable for low-frequency control applications such as ON/OFF automation.
Quick Start (Arduino Example)
A standard Arduino setup enables relay toggling within minutes using a digital output pin.
Wiring Overview
Behavior
The relay switches ON and OFF every 2 seconds, demonstrating basic functional control and system responsiveness.
