The 1-Channel 5V Relay Module is a compact switching board that lets a low-power control signal turn a higher-power device on or off. It is triggered by a 5V signal, making it a natural fit for Arduino, ESP, Raspberry Pi, and other microcontroller boards. It suits hobbyists, makers, and anyone building irrigation controllers, smart pumps, or home-automation projects who needs a reliable way to switch a single load.
Key features
- Single output channel for controlling one device at a time.
- Works with a standard 5V control signal from common microcontrollers.
- Compact board that fits easily into project boxes and prototypes.
- Screw terminals for a secure load connection and easy wiring.
- Status indicator helps confirm when the relay is switched.
Typical uses
- Switching a water pump or solenoid valve in an automated irrigation setup.
- Turning lights, fans, or small appliances on and off in a project.
- Building timers and sensor-triggered automation with Arduino or ESP boards.
- Learning and prototyping electronics and control circuits.
How to choose / tips
- Confirm your controller outputs a 5V signal so the trigger works correctly.
- Check that the device you want to switch stays within the relay's rated load.
- Use the screw terminals for a firm, tidy connection to your load.
- For multiple devices, plan how many channels your project really needs.
