Tell me about your understanding of identification technology and sensing technology. What are their similarities or differences?

One is the system and the other is the equipment.

The principle of the sensor is based on the difference of reflectivity of objects with different colors.

Sensing technology, computer technology and communication technology are also called the three pillars of information technology. From the perspective of Internet of Things, sensor technology is an important symbol to measure a country's informatization level. As the second Hangzhou Internet of Things and sensor technology application summit forum, it will promote the rapid development of sensor industrialization in China. Sensing technology is a multidisciplinary modern science and engineering technology that obtains information from natural resources and processes (converts) and identifies it. It involves the planning and design, development, manufacturing/construction, testing, application, evaluation and improvement of sensors (also known as transducers) and information processing and identification.
