The global sensor market is showing rapid growth. The market information company INTECHNOCONSULTING report, the global sensor market volume in 2008 was 50.6 billion U.S. dollars, the global sensor market in 2010 up to 600 billion U.S. dollars.
Acceleration, vibration, speed sensor is a vehicle movement sensor measurements in three major, has remained steady and strong growth momentum. Market growth acceleration sensor which is particularly obvious.

The development of automotive electronics
"No no modern automotive sensor technology" has become the industry consensus, which means that the more advanced automotive technology, the higher degree of automation, the greater the dependence on the sensor. In this regard, industry experts believe that the future application of new cars will bring about a new car with complete sensor. Most important feature of the sensor is constantly introducing new technologies to develop new features, the total development of future automotive sensor technology trend is miniaturization, multi-functional and intelligent.

Automotive sensors can be divided into three categories: power systems, safety management systems and body comfort system sensors. Power system in which the largest proportion of sensor market, embodies the most advanced automotive sensor technology. For instance, the accelerator pedal position sensor angle error must be less than 0.4%; throttle position sensor requires high reliability, and to be able to work -50 degrees to 150 degrees.

In power systems, active sensors to lead the development trend. Cam and crank sensor because the car's "heart" of the engine is closely related to a key power system. The active cam sensor and crank sensor power system can provide more protection, they will lead the future development trend. Expected in 2009, there will be 58.2 million active crankshaft sensor in use, and passive sensors will be reduced to 21.5 million.

In safety management systems, pressure sensors achieve airbag. Automotive safety management system is also widely used sensors in the field. Side air bag control vehicle acceleration sensors and pressure sensors have two options.

Trend acceleration sensor

Realized from the acceleration sensor function of view, is an internationally renowned brand of the phone, or the ordinary mobile phone, its main function is through the tilt, rock and other actions to implement the user interface control, game control and menu browsing and other control functions. At the same time, some focus on software development for customers in the development of some derivative features such as wireless mouse. In addition, the acceleration sensor can also be combined with other types of sensors (eg gyroscopes) to develop better application performance. From these new applications we can see that customers are constantly developing in depth.

    From the price point of view, the acceleration sensor of this year's prices fell by nearly half last year, down from last year's 1.5-2 U.S. dollars 1 U.S. dollar this year, the following. This price level is the popularity of the acceleration sensor, as in the past have not formed a large obstacle to the. However, because the current is very low profit margin of mobile phone products, customer price components was very strict, it should be said that now the price of the acceleration sensor is not very cheap, the cost would account for the overall cost of low-end single-digit phone percentage.
