1 Channel 5V Relay Module

1 Channel 5V Relay Module – Control AC/DC Devices with Arduino & IoT

The 1 channel 5V relay module is a compact and reliable switching component that allows microcontrollers like Arduino, ESP32, or Raspberry Pi to control AC and DC loads. It works with a 5V signal and includes an opto-isolator for safe signal isolation, making it suitable for home automation, IoT, and industrial control applications in Bangladesh.

Use it to control lights, fans, pumps, or any other high-voltage devices with just a digital pin.

Key Features:

• Operating voltage: 5V DC

• Trigger signal: 3.3V or 5V compatible (logic low trigger)

• Relay type: SPDT (Single Pole Double Throw)

• Max switching voltage: 250V AC / 30V DC

• Max switching current: 10A

• Opto-isolated input for signal protection

• Onboard power and status LEDs

Applications:

• Smart home automation

• Motor, light, and pump control

• Remote switching via Blynk or MQTT

• Arduino, NodeMCU, ESP32-based IoT projects in Bangladesh

The 1 channel 5V relay module is an essential component for safely controlling high-voltage devices with your low-voltage microcontroller.
