Gravity: Digital 5A Relay Module for Arduino
The Gravity Relay Module is a reliable, easy-to-use solution for switching high-voltage or high-current devices using low-voltage control signals from Arduino or other microcontrollers. Perfect for home automation, smart appliances, and industrial control, this digital relay module bridges the gap between high-power devices and your microcontroller projects.
Designed for plug-and-play compatibility with Arduino, this module includes a status LED for real-time visual feedback, allowing you to monitor relay activation at a glance. It supports a wide range of applications, from lighting and motors to electromagnetic valves and solenoids.

Compatibility & Notes
This relay module operates at 5V logic level and is compatible with most Arduino boards. For 3.3V systems like ESP32 or Raspberry Pi Pico, you may need a relay that supports 3.3V triggering or use a level shifter.
If you need PWM-based control such as adjusting brightness or fan speed, consider using the Gravity: MOSFET Power Controller, which is designed for smooth analog power control.
Applications
-
Smart home automation
-
Solenoid valves and electronic locks
-
High-power lighting systems
-
AC/DC motor control
-
DIY security systems
-
Industrial equipment control
