The technology used to connect devices to the Internet of Things (IoT) is typically based on wireless communication technologies such as Wi-Fi, Bluetooth, Zigbee, and cellular networks. These technologies enable devices to exchange data and communicate seamlessly. IoT devices often utilize protocols like MQTT (Message Queuing Telemetry Transport) to facilitate lightweight messaging between devices and servers. This connectivity allows for real-time data collection and monitoring, enhancing automation and control within various environments such as homes, industries, and smart cities.
