An IoT Hub is a cloud-based platform that enables communication between Internet of Things (IoT) devices and applications. It acts as a central point for managing and monitoring connected devices, allowing them to send and receive data securely. This helps businesses and developers streamline their operations and improve efficiency. With an IoT Hub, users can easily connect a wide range of devices, such as sensors, cameras, and smart appliances. The hub supports various communication protocols, ensuring compatibility across different devices. This flexibility makes it easier to build and scale IoT solutions tailored to specific needs.
