1. High precision and high quality
Assuming that the data information collected by the sensor makes a mistake, it is equivalent to making a mistake from the source, and the transmission, analysis, and use of all the data behind it will be meaningless, so the accuracy and quality of the sensor is an important baseline to ensure the vision of the Internet of Things. Imagine that if the accuracy and quality of the sensors in an intelligent connected car are not up to standard, this means that the system will not be able to make the right decision plan within a few milliseconds of an accident, and then seriously threaten the safety of the driver.
2. Miniaturization
As mobile devices such as smartphones move toward multi-functionality and high performance, there is a need for a larger number of components and a smaller size in the board. As a result, sensors are increasingly adopting integrated skills to achieve high performance and miniaturization. Integrated temperature sensors, integrated pressure sensors, etc. 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 power, and we have long been accustomed to charging every day and going out to power the treasure without leaving the day, but can you imagine what a bad situation it would be to assume that smoke alarms, smart cameras and other connected devices also need to replace the battery every day? Unlike mobile phones, many IoT devices are located in areas that people do not often touch, so there are ** requirements for power consumption, and then it is decided that the power consumption of the sensor should also be very low, otherwise the operating cost is too high.
4. Intelligent
With the proliferation of connected devices, the explosive growth of data, the centralized cloud has been "overwhelmed", and more importantly, for use scenarios such as intelligent manufacturing or intelligent transportation, the postponement of cloud analysis will cause the value of data to fall "cliff-like", so marginal intelligence has begun to bulge.
The sensor is a good marginal node, and the embedded skills are used to integrate the sensor and the microprocessor into one, making it an intelligent data terminal device with environmental perception, data processing, intelligent control and data communication functions, which is the so-called intelligent sensor. The sensor is self-learning, self-diagnosing and self-compensating, composite sensing, and sensitive communication. In this way, the data fed back to the Internet of Things system by the sensor when perceiving the physical world will be more accurate and comprehensive, so as to achieve the purpose of perception.

High-frequency pressure sensor output signal – ifm
The conversion of the pressure to the electrical signal is done by the physical deformation of the strain gauge, and the strain gauge is bonded to the diaphragm of the pressure sensor and wired into a Wheatstone bridge structure. The pressure exerted on a high-frequency pressure sensor causes the diaphragm to flex, which causes the strain gauge to strain. Strain will occur ...
