Application Fields of Sensor Technology in Internet of Things


Sensors have been widely used in aerospace, aviation, national defense, science and technology, industrial and agricultural production and other fields. For example, it has broad application prospects in the field of robotics. Smart sensors enable robots to have human-like facial features and brain functions, perceive various phenomena, and complete various actions.


In industrial production, some product quality indicators (such as viscosity, hardness, surface finish, composition, color and taste, etc.). Conventional sensors cannot take measurements quickly and directly. Smart sensors can directly measure temperature, pressure, flow, etc. There is a functional relationship between it and the product quality index, and the mathematical model established by using neural network or expert system technology can be used to calculate the product quality.


With the continuous breakthroughs in the further development of sensor technology and products, the sensor application market continues to deepen. Among them, the fields of fingerprint identification and autopilot have always been promising industries, and industries such as robotics and medical treatment may become new fertile ground for the future development of sensors.


Specifically, in the field of autonomous driving, due to the limited space of the body itself, ordinary sensors obviously cannot meet the new requirements of the times, and the advantages of smart sensors are highlighted. Compared with traditional sensors, smart sensors can not only achieve accurate data collection, but also control the cost within a certain range. In addition, its automation capabilities and diverse functions also add a lot of highlights to smart sensors.


For example, the Google car, in addition to the laser scanner, uses parts/systems of sensor technology such as cameras, radar and inertial. At present, the commonly used sensors for vehicle autonomous driving include lidar, image sensor, millimeter wave radar and so on.


Autopilot is just a sensor solution, and the bigger market is the promising application of fingerprint recognition. In the past two years, the development speed of smart phones is very fast, and equipped with fingerprint recognition has become an essential function of a small brand of smart phones. The data shows that in 2016, it was almost equal to 700 million fingerprint sensors, exceeding a compound annual growth rate of 133%.


With the continuous development of smart products such as smartphones, wearable devices, and smart door locks, the fingerprint sensor market will usher in a brighter future. In the era of the Internet of Things, how should the sensor industry go?


At present, the Internet of Things industry is still in the stage of concept introduction and the gradual formation of the industrial chain in the world, and the technical standards and systems of all parties are still in rapid iteration. The process of its internal logical evolution has produced obvious self-subversive effects, and the overall industry is on the eve of brewing and erupting, but only this period has the most opportunities.


The emergence of the Internet era has given birth to a series of big hits such as e-commerce, social networking, and financial technology. Then the answer to who will get the hits in the Internet of Things era will soon be revealed.
