The Internet of Things has been hailed as the most important change in the IT industry in 10 years. The impact will even exceed that of the Internet. The architecture of the Internet of Things can be roughly divided into three parts, including the first-level sensing network, Layer 2 communication, and the third. Layer data storage analysis, Layer 4 applications, from the perspective of the architecture, sensing layer is the foundation of the overall Internet of things, through the data collected by various sensors, will be assembled into a huge database for back-end decision-making With the help of the formulation, sensing technology will be the first key to the success or failure of the Internet of Things.
In the IT market, sensing is not a new technology. Not only is the technology mature for a long time, but the application is already widely used. Sensors are the first line of sensing networks. In terms of technology, motion sensing is currently the most popular technology, and audio sensing is still In the development state, but the future has considerable potential for development.
Looking ahead to the technology trend of the future, whether it is the Internet of things or wearable devices, the future sensing components still have several common trends, the first is the system multi-axis, the sensing system toward multi-axis development is an important trend in the sense of the application market In fact, the multi-axis movement of the sensing system has never stopped, from the early generation of single-axis sensors, to the current common three-axis, six-axis, nine-axis, ten-axis, and eleven-axis, and even the latest 12 Axis sensing system, multi-axis is already an irreversible path.
What are the axes of the so-called "multi-axes" of sensors? Which axes are necessary and which are only secondary? Generally speaking, from triaxial accelerometers, triaxial gyros to triaxial electronic compasses, these 9 Axis has almost become the standard equipment for smart phones. Through these three types of sensors, almost all applications can be completed. This can be called the "three major axes" in the sensing system.
In addition to these three types of sensors, altimeters, pressure gauges, thermometers, and photosensors, etc., have all been added to the sensing system and become one of the members of multi-axis. Since multi-axis is an established trend, the future will be More manufacturers continue to develop more shaft sensing platforms to meet market application requirements.
