1, high precision and high quality

If the data information collected by the sensor is wrong, it is equivalent to an error from the source, and the transmission, analysis and application of all subsequent data will be meaningless. Therefore, the accuracy and quality of the sensor is an important baseline to ensure the vision of the Internet of Things. Imagine if the accuracy and quality of an intelligent networked automobile sensor are not up to standard, which means that the system can't make correct decisions within a few milliseconds of the accident.

2. Miniaturization

With the development of mobile devices centered on smart phones to multi-function and high performance, it is required that the number of components in the circuit board is more and the volume is smaller. Therefore, sensors are gradually adopting integrated technology to achieve high performance and miniaturization. Integrated temperature sensors and integrated pressure sensors have been widely used for a long time, and more integrated sensors will be developed in the future.

3. Low power consumption

Weibo, WeChat, video and games on mobile phones are all big consumers of electricity, and we have long been accustomed to the days when we charge and go out for a long time, but can you imagine what a lame scene it would be if interconnected devices such as smoke alarms and smart cameras also need to change batteries every day? Different from mobile phones, many IOT devices are located in areas that people don't often touch, so they have excellent requirements for power consumption, which determines that the power consumption of sensors should be very low, otherwise the operating cost is too high.

4, intelligent

With the proliferation of connected devices, the data has exploded, and the centralized cloud has become "overwhelmed". More importantly, for application scenarios such as intelligent manufacturing or intelligent transportation, the delay of cloud analysis will make the data value fall "cliff-like". As a result, edge intelligence began to rise.

The sensor is a good edge node. The embedded technology is used to integrate the sensor with the microprocessor, making it an intelligent data terminal device with the functions of environment perception, data processing, intelligent control and data communication. This is the so-called intelligent sensor. This sensor has the abilities of self-learning, self-diagnosis and self-compensation, composite sensing and flexible communication. In this way, when the sensor senses the physical world, the data fed back to the Internet of Things system will be more accurate and comprehensive, so as to achieve the purpose of perception.
