The technology relevant for the Internet of Things (IoT) devices to communicate effectively is Wireless Sensor Networks (WSNs), along with various communication protocols such as MQTT and CoAP. These technologies enable IoT devices, which often include sensors and actuators, to transmit data over the internet or local networks. Reliable communication protocols facilitate low-power and efficient data exchange, essential for real-time processing and analytics. Together, these technologies enable smart applications that improve efficiency, automation, and remote monitoring across industries.
