1 CH 5V Active Low Relay Board

A 1-Channel 5V Active Low Relay Board is a compact module used to control high-voltage devices like lights, fans, or motors with low-voltage signals. It operates on a 5V input and is activated by a low-level signal, meaning the relay switches when the control input is brought to ground (low). This relay board is ideal for microcontroller projects (such as Arduino or Raspberry Pi) and provides isolation between low-power control circuits and high-power loads for safe and reliable switching in automation projects.
