The 1-Channel Relay Module is a compact switching board that lets a low-power control signal turn a larger circuit on or off. It accepts a 5V, 12V, or 24V trigger signal, which makes it flexible for a wide range of controllers and power setups. It is a popular building block for home garden automation, small farm projects, hydroponics rigs, and any DIY system where you need to control a pump, valve, light, or fan electronically.
Key features
- Single output channel for switching one device or circuit at a time.
- Works with a 5V, 12V, or 24V control signal for broad compatibility.
- Simple, beginner-friendly wiring suitable for hobby and project use.
- Compact board that fits easily inside enclosures and control boxes.
Typical uses
- Automating irrigation pumps and solenoid valves on a timer or controller.
- Switching lights, fans, or small appliances in greenhouses and grow setups.
- Adding remote or scheduled control to home automation and DIY electronics.
How to choose / tips
- Match the relay's control voltage (5V, 12V, or 24V) to the signal your controller or board outputs.
- Confirm the load you want to switch stays within the relay's rated capacity.
- Keep control wiring and load wiring tidy and well insulated inside a box.
