The technology essential for implementing machine-to-machine communication includes Internet of Things (IoT) devices, wireless communication protocols, and cloud computing. IoT devices are equipped with sensors and software that enable them to collect and exchange data autonomously over the internet. Wireless protocols, such as MQTT and HTTP, facilitate seamless data exchange among machines. Furthermore, cloud computing platforms provide the necessary infrastructure for data storage and processing, enabling real-time analysis and action based on the data collected from various devices, improving efficiency and automation across industries.
