Relay Module

Overview:

The 5V Relay Module is a high-quality, electrically isolated relay designed to control high-voltage devices such as lights, motors, fans, and home appliances using low-power microcontrollers like Arduino, ESP32, Raspberry Pi, and other development boards. It features optocoupler isolation for enhanced protection and a built-in flyback diode to prevent voltage spikes.

Key Features:

✔ 5V Trigger Voltage: Compatible with most microcontrollers (Arduino, ESP32, Raspberry Pi, etc.).
✔ High Voltage Switching: Can switch up to 250V AC / 30V DC at 10A.
✔ Optocoupler Isolation: Provides electrical separation for better safety.
✔ Indicator LED: Shows relay activation status.
✔ Normally Open (NO) & Normally Closed (NC): Supports both switching modes.
✔ Screw Terminals: Secure and easy connections for external devices.

Technical Details

How It Works:

1. Power the Relay Module: Connect VCC (5V), GND, and IN (control pin) to a microcontroller.
2. Control with Microcontroller:
   • Send HIGH (5V): Activates relay, allowing power to flow.
   • Send LOW (0V): Deactivates relay, cutting off power.
3. Connect Load: Use NO (Normally Open) or NC (Normally Closed) contacts to control AC/DC devices.

Applications:

💡 Smart Home Automation: Control lights, fans, and appliances remotely.
🔌 Industrial Automation: Automate machinery and electrical circuits.
🔋 Battery Management Systems: Control charging/discharging circuits.
🛠 DIY Electronics Projects: Works with Arduino, ESP32, and Raspberry Pi.
🚗 Automotive Projects: Switch 12V car electronics using microcontrollers.

Package Includes:

✔ 1 x 5V Relay Module (Single Channel)
