Samsung Galaxy A52s (8GB/128GB)

Proximity Sensor

Detects when an object is near to the phone. Most commonly used to sense when a phone is held up to the users ear to turn off the display. This saves both battery life and prevents accidental screen touches.

Accelerometer and gyroscope

Accelerometers in mobile phones are used to detect the orientation of the phone. The gyroscope, or gyro for short, adds an additional dimension to the information supplied by the accelerometer by tracking rotation or twist.

An accelerometer measures linear acceleration of movement, while a gyro on the other hand measures the angular rotational velocity. Both sensors measure rate of change; they just measure the rate of change for different things.

In practice, that means that an accelerometer will measure the directional movement of a device but will not be able to resolve its lateral orientation or tilt during that movement accurately unless a gyro is there to fill in that info.

With an accelerometer you can either get a really “noisy” info output that is responsive, or you can get a “clean” output that’s sluggish. But when you combine the 3-axis accelerometer with a 3-axis gyro, you get an output that is both clean and responsive in the same time.”

Accelerometers are also used to provide ‘steps’ information for a vendors ‘health’ application.

Digital compass

The digital compass that’s usually based on a sensor called the magnetometer and provides mobile phones with a simple orientation in relation to the Earth’s magnetic field. As a result, your phone always knows which way is North so it can auto rotate your digital maps depending on your physical orientation.

Barometer

The barometer assists the GPS chip inside the device to get a faster lock by instantly delivering altitude data. Additionally,

the barometer can be utilized to provide ‘floors climbed’ information to a phones ‘health’ app.

With the advent of more accurate indoor navigation, the barometer can assist in determine what floor a user is on within an airport for example.

Biometrics

Biometric related sensors provide levels of enhanced security by capturing and validating human related metrics. Including Finger Print recognition, IRIS (eye) scanning and full facial recognition.

Biometric sensors provide a more secure but more convenient way to unlock phones and pay for purchases.

Additionally, biometric sensors can be used to collect a users heart rate and SpO2 (the estimate of arterial oxygen saturation) for use within a vendors ‘health’ application.

Augmented & Virtual Reality

The highly accurate sensors detailed above, when combined with the powerful CPU & GPU’s of modern smart phones, allow very realist and responsive Virtual Reality applications to be created. When the sensors are combined with a smartphones camera they facilitate Augmented Reality applications.
