IPhone 5S sensor detection

IPhone 5S sensor detection When playing a racing game, obviously control is correct but the total deviation affects the record? The map pointers northeast and northwest directions often make you unable to find the way? It's all the sensors!

At the end of 2013, component trading network planned a vigorous test - [small sensor] a large inventory of mobile sensor performance, using the scientific method and rigorous attitude to test the current "popular" model, to restore you a real "sensor ".

The smart machine we tested today is the iPhone 5S.

First, the test situation is now with us, explore the iPhone 5S built-in sensor performance!

You may be puzzled to see our topic, sensor ... is a yo?

"Shake it", "shut off the screen and cut the song", "automatic screen" is the work of the gravity sensor, 3D game conversion vision requires the coordination of the gyroscope, electromagnetic compass? This is the "electronic compass". The small arrow inside our map application is used to control it.

As for the gesture solution? If you've used a wearable device that monitors sports, then it's a widget that measures your movements.

For smart phones, sensors have become an indispensable and important component, giving mobile users more functional experience. General mobile phone evaluation, the sensor is limited to the kind of statistics, such as "this machine is equipped with acceleration and gyro sensor."

The evaluation of the component trading network aims at relatively detailed evaluation of the common sensors of the mobile phone, horizontally comparing the sampling frequency, accuracy, noise level, and attitude calculation accuracy of each mobile phone, in order to objectively analyze the mobile phones. The sensor configuration is evaluated.

You see the officer take a deep breath and the assessment begins immediately!

Let us first read the sampling frequency of the iPhone 5S accelerometer, gyro, and electromagnetic compass.

The sampling frequency of sensors in different mobile phones is generally between 50-300 times. The sampling frequency of the iPhone 5S acceleration sensor is 100 times/second, the sampling frequency of the gyro sensor is 100 times/second, and the sampling frequency of the electromagnetic compass sensor is also 50 times/second. In addition to the addition of electromagnetic compass sampling frequency is slightly lower, the other two are passing.

The next step is dry goods. We need to evaluate the offset, noise, and noise levels of the three sensors, the acceleration sensor, the gyroscope, and the electromagnetic compass, when they are standing still.

Every mobile phone on the market is attached to "local gold", pay attention! The real "local gold" is approaching.
