As a new scientific and technological product, it can sense the physical height, especially suitable for mobile applications, such as indoor navigation, altitude measurement, fitness and weather forecast. Hp203b high precision 1m air pressure sensor launched by Huapu is the first in the industry, with ultra-low power consumption and extreme power saving. It can directly output the air pressure, altitude and temperature values, and has been widely used in the fields of weather forecast, three defense mobile phones, 3D navigation, model aircraft toys and so on.
Spring of pressure sensor
According to statistics, by 2016, the overall market scale of China's Internet of things will reach or reach 750 billion yuan, and the sensor industry will directly benefit from it. It is predicted that China's sensor market will develop steadily and rapidly in the next five years. Driven by the rapid growth of the market scale of the Internet of things, the scale of China's sensor market is expected to reach about 121.3 billion yuan in 2016.
The four major application fields of sensors in China are consumer electronics, industry, automotive electronics and special equipment for communication electronics. With the development of innovative application fields such as smart phones, smart wearables and consumer electronics, the market share of pressure sensors is also steadily increasing, and it is expected to create more market demand in the future.
The products of China's sensor enterprises are mainly low-end products, and the import of high-end products accounts for a large proportion, including about 60% of sensors, about 80% of sensor chips and almost 100% of MEMS chips. In recent years, the Ministry of industry and information technology has successively issued the 12th Five Year Plan for the development of the Internet of things and other relevant policies. At present, China's sensor industry has formed a complete industrial system from technology research and development, design, production to application with the support of national policies. Medium and low-end products basically meet the market demand, but high-tech products are insufficient; At the same time, there is a serious shortage of digital, intelligent and miniaturized products. At the same time, the market demand of sensor products is in the stage of rapid transformation from traditional to new sensors. The new sensors are characterized by miniaturization, digitization, intelligence, multi-function, systematization and networking. It not only promotes the transformation of traditional industries, but also is a new economic growth point in the 21st century.
From the overall global situation, a small number of economically developed countries such as the United States and Japan account for more than 70% of the sensor market, while developing countries account for a relatively small share. Among them, the three countries with the largest market size are the United States, Japan and Germany.
As a group company of the Internet of things service industry chain, Huapu has been focusing on the core technologies of RF and pressure sensors for 18 years. Since 2010, it has focused on the research and development of sensor chips. Now it has become the only company in China with the ability to design MEMS sensor chips, filling the gap in China.
The growth soil of the new sensor is derived from the core technical ability and innovation ability. Huapu has more than 80 top R & D and design teams in the world, of which more than 60% have the working experience of international first-class enterprises such as Germany, the United States and Switzerland. It is precisely this rich top-level technical atmosphere that Huapu has so far obtained 18 patents in the field of pressure sensors, including appearance design and utility model, and 5 software copyrights. China's sensor manufacturing enterprises are mainly concentrated in the Yangtze River Delta region, and gradually form a regional spatial layout dominated by central cities such as Beijing, Shanghai, Nanjing, Shenzhen, Shenyang and Xi'an. Huapu has a modern production base of 30000 square meters in Wuxi Taihu science and Technology Park in the Yangtze River Delta. It has introduced first-class packaging, testing and production equipment and high-precision testing and measuring instruments from Germany and the United States. It conducts production management in strict accordance with the ISO9001 international quality certification system, fully ensuring the reliability and stability of product quality.
Application of Huapu pressure sensor in wearable Market
Since the beginning of this year, smart wearable devices have become the highlight of major exhibitions, with a momentum of catching up with and surpassing smart phones and various tablet products. According to the IMS report, the smart wearable device market is expected to reach 171 million shipments in 2016, while the shipments in 2011 were only 14 million. According to ABI's latest forecast, the annual shipment of smart wearable devices will reach 485 million in 2018.
Wearable devices include sports watches, fishing barometers, outdoor waterproof equipment, etc. for those who like to climb mountains, they will be very concerned about their height. There are two commonly used methods for measuring altitude: one is through the GPS global positioning system, and the other is through measuring the atmospheric pressure, and then calculating the altitude according to the atmospheric pressure value. If the absolute MEMS pressure sensor with a full range of 300 mbar to 1100 mbar is used, the measurement height can reach 9165 meters above sea level to 698 meters below sea level. Absolute error: 15m, relative error: 10 ~ 20cm. The contents displayed at the same time can be completely customized, with a maximum of 6 displays. You can select temperature, slope, climbing height, distance from the end point, distance from the peak, uphill height, downhill height and other data. At the same time, for the elderly, there are more intelligent anti falling bracelets to ensure the personal safety of the elderly through timely alarm.
Application of Huapu pressure sensor in smart phone
In its latest report on predicting the development trend of the global smartphone market, Market Research Institute IDC pointed out that the growth rate of China's smartphone market is slowing down. As for the slowing smartphone market in China, Leopold beer said that there are still many sensors that have not been applied in smartphones, and pressure sensors are one of them. It can sense the physical height, especially suitable for mobile applications, such as indoor navigation, altitude measurement, fitness and weather forecast.
Hp203b high precision 1m air pressure sensor launched by Huapu is the first in the industry, with ultra-low power consumption and extreme power saving. It can directly output the air pressure, altitude and temperature values, and has been widely used in the fields of three defense mobile phones, weather forecast, 3D navigation, aviation model toys and so on.
The pressure sensor was first used in smart phones on galaxy nexus, and some Android flagship phones launched later also included pressure sensors, such as Galaxy S III, Galaxy note 2 and Xiaomi 2. However, we are still very unfamiliar with pressure sensors. In fact, pressure sensors are used to measure atmospheric pressure in mobile phones, but what is the role of measuring atmospheric pressure for ordinary mobile phone users? Originally, the pressure sensor function was added on the basis of the original GPS of the smart phone, which can make the three-dimensional positioning more accurate.
Auxiliary navigation
Many motorists now use their mobile phones to navigate, but some people often complain that navigation in viaducts often makes mistakes. For example, when you are on the viaduct, the GPS says to turn right, but in fact, there is no right turn exit on the right. This is mainly due to the GPS's failure to determine whether you are on or under the bridge. Generally, the height of the upper and lower floors of the viaduct will be several meters to ten meters, and the GPS error may be several tens of meters, so it is understandable that the above things happen.
However, if a pressure sensor is added to the mobile phone, it will be different. For example, the height accuracy of the pressure sensor of Huapu has reached the accuracy value of 1 meter, which can help GPs to measure the height, and the problem of wrong navigation can be easily solved.
Indoor positioning
Because the GPS signal cannot be received well indoors, when the user enters a very thick building, the built-in sensor may lose the satellite signal, unable to recognize the user's geographical position and unable to sense the vertical height. If the mobile phone is combined with the Huapu pressure sensor and the accelerometer, gyroscope and other technologies, accurate indoor positioning can be achieved. In this way, when users shop in the mall, they can tell you the location and floor of the product they want to buy in the mall through mobile phone positioning.
In addition, Huapu's pressure sensor can also provide fishing enthusiasts with relevant information (fish stratification and activity are related to atmospheric pressure) or weather forecast. To be understood and used by more people, the pressure sensor needs to be gradually mature in the market, as well as the maturity and popularization of related technologies. Huapu will deeply settle and innovate again, and is committed to creating more perfect applications and functions for the intelligent life consumption field.
