What is a 5V Single Channel Relay Module? 🤔
A 1-channel 5V DC relay module is designed to control high-power devices using a low-power microcontroller or other control signals. Let’s break down its key components and features:
⭐Channel: The term “1-channel” indicates that this relay module can control a single device or circuit. The relay can turn the device on or off.
⭐Relay: A relay is an electromagnetic switch that allows a low-power circuit (controlled by a microcontroller or similar) to control a higher-power circuit or device.
⭐Voltage Rating: The module operates at a voltage of 5V DC, which means it requires a 5V DC power supply to function.
⭐LED Indicators: Many relay modules have LED indicators that show the status of the relay (whether it’s active or not).
