The function of pressure sensor in smart phone

Release date: July 6, 2019 Hits: 95

There are many sensors used in smart phones, such as distance sensor, image sensor, pressure sensor and so on. Today, let's talk about the use of the pressure sensor in the smart phone. The pressure sensor in the smart phone is indispensable. What is the function of the pressure sensor in the smart phone? Let's introduce it for you.

Auxiliary navigation

Nowadays, many drivers will use their mobile phones for navigation, but some people often complain that the navigation in the viaduct often makes mistakes. For example, when you are on the viaduct, GPS says to turn right, but actually there is no right turn exit on the right. This is mainly because GPS can't judge whether you are on the bridge or under the bridge, resulting in wrong navigation. If the height of the viaduct is more than ten meters, it can be understood that the distance between the upper and lower layers of the viaduct will be a few meters, so it can be understood that the distance between the upper and lower layers of the viaduct will be a few meters.

If a pressure sensor is added to the mobile phone, it will be different. Its accuracy can be up to 1 meter. In this way, it can help GPs to measure the height, and the problem of wrong navigation can be easily solved.

Indoor positioning

Because GPS signal can not be received well indoors, when users enter a very thick building, the built-in sensor may lose the signal of satellite, so it is unable to identify the user's geographical location and can not sense the vertical height. If the mobile phone with pressure sensor and accelerometer, gyroscope and other technologies can achieve accurate indoor positioning. In this way, when you are shopping in the mall, you can tell the location and floor of the product you want to buy through the location of your mobile phone.

Through the above introduction, we all know what the functions of pressure sensors in smart phones are. Pressure sensors are very helpful for mobile phones. These functions are indispensable for smart phones. Installing pressure sensors on smart phones can make mobile phones more intelligent.
