In recent years, the rise of the Internet of Things (IoT) has revolutionized the way we interact with technology, creating new possibilities for home automation, industrial control, and smart systems. One of the key components that enable remote and automated control of devices is the IoT Relay Module. This versatile tool bridges the physical world with the digital realm, allowing users to control electrical devices remotely, opening up a vast range of applications across various industries.

What is an IoT Relay Module? An IoT Relay Module is a device that connects an IoT platform (such as a Wi-Fi or Bluetooth-enabled controller) with an electrical circuit, making it possible to control high-voltage or high-power devices remotely. The module typically consists of a relay switch, which acts as an electrically controlled switch, and the IoT communication interface that connects it to the network. The relay allows you to control large appliances such as lights, fans, air conditioners, and industrial machines, all through a simple network connection. Users can toggle the relay between “open” and “closed” states, thereby turning connected devices on and off without physically interacting with them.
