Final answer:
Machine-to-machine communication is critical in smart factories, smart metering, and traffic management systems, enabling automated processes, efficient data collection, and real-time traffic control.
Step-by-step explanation:
An example of machine-to-machine communication can be seen in modern manufacturing and industrial processes. For instance, in a smart factory setting, different machines such as sensors, conveyor belts, and robotic arms communicate with each other to optimize production without human intervention. A sensor on a production line might detect a finished product and instruct a robotic arm to move the product to the next stage. Similarly, the conveyor belt system might adjust its speed based on feedback from the machines performing the assembly tasks.
Smart metering in utilities is another example. Here, electricity meters at customer premises record usage data and communicate it back to the utility provider's systems for monitoring and billing. This communication allows for more accurate and timely data collection, reducing the need for manual meter readings and providing insights into usage patterns.
Finally, traffic management systems often use machine-to-machine communication to control traffic lights and signage. Traffic flow sensors detect congestion and communicate with traffic control centers, which can then change traffic light sequences to alleviate bottlenecks and improve overall traffic flow.
