Description
1 Channel 5V Relay Module with Optocoupler for Arduino & ESP32
The 1 Channel 5V Relay Module with Optocoupler is a reliable switching module designed to control high-voltage AC or DC devices using low-voltage microcontrollers. It features an optocoupler (optical isolation) to improve electrical isolation between the control circuit and the relay, making it suitable for Arduino, ESP32, Raspberry Pi, STM32 and other embedded development platforms.
This relay module is widely used in home automation, IoT systems, industrial automation, robotics, security systems, smart appliances and DIY electronics. It allows microcontrollers to safely switch lamps, fans, pumps, motors, solenoid valves and other electrical loads through a simple digital control signal.

Frequently Asked Questions (FAQs)
What is the purpose of the optocoupler?
The optocoupler electrically isolates the control circuit from the relay circuit, helping reduce electrical noise and improving safety for the connected microcontroller.
Is this module compatible with Arduino?
Yes. It works perfectly with Arduino Uno, Nano, Mega, Pro Mini and other Arduino-compatible boards.
Can I use this module with ESP32?
Yes. The relay module is compatible with ESP32, ESP8266 and most other microcontrollers using digital GPIO pins.
What devices can I control with this relay?
You can control AC lights, fans, pumps, solenoid valves, small motors, alarms and other electrical loads within the relay's rated voltage and current limits.
Can this relay switch both AC and DC loads?
Yes. The relay supports switching both AC and DC loads, provided they do not exceed the module's specified ratings.
