The WZP platinum resistance temperature sensor Pt1000 is a device that uses the characteristic of electromagnetic parameters of components changing with temperature to detect temperature related parameters. Due to its relatively good linearity, strong oxidation resistance, and wide temperature range, its temperature measurement range is from -200 ℃ to+650 ℃, and it is currently widely used in industrial production and scientific research. The signal processing circuit of the sensor needs to convert the resistance change signal related to temperature into a unified voltage signal. The output characteristic curve of Pt1000 was measured by placing Pt1000 in a high and low temperature experimental chamber and setting the temperature to -30 ℃ to+70 ℃. The resistance values of the temperature sensor were measured at different temperatures, and the measured data are shown in Figure 1. Within the temperature measurement range, Pt1000

Sensor materials are an important foundation of sensor technology, and with the advancement of materials science, people can manufacture various new types of sensors. For example, temperature sensors can be made from polymer films, optical fibers can be used to make various sensors such as pressure, flow, temperature, displacement, etc., and pressure sensors can be made from ceramics. Polymer can adsorb and release water molecules in proportion to the relative humidity of the surrounding environment. By making a polymer dielectric into a capacitor and measuring the change in capacitance, the relative humidity can be obtained. The plasma polymerization polystyrene film temperature sensor made using this principle has the characteristics of wide humidity measurement range, wide temperature range, fast response speed, small size, can be used for small space humidity measurement, and small temperature coefficient. Ceramic capacitive pressure sensor is a dry pressure sensor without intermediate fluid

With the development of science and technology, all industries cannot do without the word "intelligence", from intelligent industry, intelligent agriculture, intelligent transportation, to different fields such as intelligent logistics and intelligent security. The demand for intelligence in various fields is essentially the continuous enhancement of information needs. Sensors have become one of the important electronic devices that urgently need to be developed, especially intelligent sensors that can collect, process, analyze, and transmit information. In information consumption, accuracy, timeliness, and wide coverage of information sources are the foundation, and sensors are one of the important media among them. Traditional sensors can meet this demand, but they are unable to analyze and process information, which is fatal for performance intensive electronic components. Therefore, smart sensors have emerged. Wisdom

Fiber optic sensors have always been highly regarded as an extremely important component of the Internet of Things. From a global market perspective, the global fiber optic sensor market size in 2013 was 1.89 billion US dollars. It is expected that the global fiber optic sensor market will grow at an average annual rate of 18% from 2014 to 2018, reaching a market size of 4.33 billion US dollars by 2018. From the perspective of fiber optic sensing technology research, the United States started researching this technology earliest and is the most advanced in the world. Data shows that in 2007, the market size of fiber optic sensors in the United States was $235 million, and it has been growing at a compound annual growth rate of 30 years since then. It is expected to reach $1.6 billion in 2014. Compared to the United States, China's fiber optic sensing industry is in its infancy. According to statistics, as of the end of 2013,

On the highway between San Francisco and Los Angeles in the United States, a Toyota Prius hybrid electric vehicle with a video camera installed on the roof has recently appeared. Although there is a person sitting in the driver's seat, no one is driving. This is an autonomous vehicle that Google is secretly developing, using artificial intelligence software to sense various things around the car and simulate the operation of a real person driving. At present, Google has 7 such test vehicles, one of which has driven 140000 miles without any human intervention, and the other has even traveled on one of the steep and winding roads in the United States - Lombard Street in San Francisco. It is reported that these vehicles have only been involved in one car accident, and were rear ended by a vehicle behind them while parked at a traffic light.

With the rapid development of industries such as mobile intelligence and the Internet of Things, there is an increasing demand for high precision and intelligence. In order to enable customers to complete system development faster and more conveniently, some sensor manufacturers have begun to provide more advanced modular development platforms, namely MCU+sensors, to enhance their information processing capabilities. This has gradually become a new technological trend. However, MCU+sensors require more complex digital analog hybrid manufacturing processes. It is necessary to carefully observe where this development trend can go in the future and how Chinese companies can adapt to this trend.
