    The Internet of Things (IoT) has revolutionized the way we interact with everyday objects and systems. One of the crucial components that enables seamless connectivity and automation is the IoT Relay Module. These modules serve as a bridge between low-voltage control circuits and high-voltage electrical devices, allowing remote control of various appliances and machinery. In this article, we’ll dive into the fundamentals of IoT Relay Modules, their functionality, and the wide array of applications they support.

    What is an IoT Relay Module?
    An IoT Relay Module is an electronic device that integrates a relay (an electrically operated switch) with IoT technology to enable the remote control of electrical devices. The primary function of a relay is to switch a high-current load using a low-current control signal. In IoT applications, the relay module is connected to a microcontroller or microprocessor that communicates over a wireless network (such as Wi-Fi, Bluetooth, Zigbee, or LoRa) to control the relay. This allows users to turn on or off electrical devices, such as lights, motors, and home appliances, from anywhere in the world using a smartphone, tablet, or computer.
