The internet has undergone a long process of development, and each device has a separate IP address. The machine-to-machine (M2M) communication is also upgraded, without the need for human intervention, information exchange and processing between devices. The scope and scale of the Internet has changed dramatically. The challenge in the embedded world is how to increase the value of the Internet. This is the value of the Internet of Things (IoT). Peng Zhichang pointed out that the challenge of implementing device interconnection applications for the Internet of Things is completely different from the challenges of traditional network connection devices. Peng Zhichang, senior marketing manager of Silicon Labs Asia Pacific MCU, said that the terminals of the Internet of Things are the devices that people use every day. These "things" are interconnected by a communication standard such as a ZigBee, Sub-GHz, Wi-Fi or PLC connected infrastructure or backbone network. However, the main connection in the Internet of Things is the so-called "last inch" node in the network. These nodes contain microcontrollers (MCUs), wireless devices, sensors, and actuators, which are the brain, eyes, and fingers of the Internet of Things. The goal of the Internet of Things is not the connection between the user and the device. After all, the user does not want to monitor the sensors at home. The goal of the Internet of Things is to not only collect important information, but also to communicate with each other and make important decisions. Peng Zhichang pointed out that the challenge of implementing device interconnection applications for the Internet of Things is completely different from the challenges of traditional network connection devices. For example, OEMs such as lighting and home appliances, in addition to their core functions, are introducing new networking, wireless and embedded software technologies. In addition, since the device is usually not connected to the power source, the power supply efficiency is also critical, requiring years of operation with energy harvesting devices or batteries without maintenance or replacement of the battery. Developers also need to consider other factors such as cost, component count, MCU performance, system size, standards, interoperability, security, ease of use, and on-site troubleshooting capabilities. Finally, the software must be able to bridge devices, aggregate sensor data, and display information to the user through the display in an intuitive manner, or via the network to a user's computer, tablet or mobile phone. Smart meters are a typical example of IoT applications. In addition to simply measuring power consumption, smart meters enable power companies to communicate instantly with customers, actively shutting down high-load appliances at peak usage levels, saving electricity bills for users, and mitigating load for power companies. In fact, smart meters are just one of the applications of the Internet of Things in smart homes. The Internet of Things can not only benefit industrial automation, lighting control, smart home, security and surveillance, health and wellness, but also agricultural applications. The emerging Internet of wearable applications can also see the Internet of Things. Peng Zhichang said that the current Internet of Things solutions from Silicon Labs can completely cover the sensors, MCUs, wireless transmissions and analog components of the Internet of Things, enabling related manufacturers of IoT devices to have more peace of mind in product design.
