List Of Smartphone Sensors Explained

Today’s every smartphone is coming with a set of sensors. There are several lists of sensors are equipped with smartphones for getting things done. So what are these smartphone Sensors useful for? This guide will help you to know about every sensor present on your mobile.

Smartphone Sensors Wiki


The gyroscope is an orientation sensor with accurate precision. It simply calculates the angular velocity of the device. The gyroscope in smartphones is used for tracking rotation of the device. When you play games like N.O.V.A, Modern Combat: Sandstrom you can feel rotation, and axis. The gyroscope calculates data along with accelerometer and sends the data to the game.

Popular apps like Google Sky Map, Android Photo Sphere camera, and much more apps uses the Gyroscope data for accurate results.


Accelerometer measures and calculates the device acceleration. It calculates the three axis orientation of the device and sends the data to the required apps and games.

For example, in Android, you can use portrait or landscape mode. When you move the smartphone in portrait and landscape modes the phone screen, automatically adjust according to the position with the help of accelerometer. It is one of the most widely used android phone sensors.

Proximity Sensor (what is proximity sensor in mobile?)

When you are on the call and place the phone near to the ear the light turns off, ever wondered how it works? A Proximity Sensor in mobile will detect the near object and send the data to your phone. The sensor works by activating a small beam of light which is reflected by our skin and the device turns off the screen display temporarily.

Light-Sensor (Ambient light sensor in mobile)

Light Sensor is used in Smartphones for automatic display light adjustment. This sensor calculates the Illuminance of the environment and sends the data to the device. Then the device calculates the required display brightness and applies the effect.

Barometer (What is barometer sensor in mobile?)

Barometer is a sensor which we usually find in high-end smartphones. As we know from the school Physics Barometer measures the atmospheric pressure. However, there is no direct use in smartphones; the Barometer in mobile works with GPS sensor about the device sea level measurements for greater GPS accuracy.

Heart Rate Monitor

As it name implies this sensor measures the heart rate of the user. It measures the heart rate by placing the user’s finger on the sensor. It calculates the user pulse by minute wise and displays on the screen.

Fingerprint Sensor

Fingerprint sensor doesn’t need any introduction. This sensor became most common these days, and it is coming equipped even on a low-end smartphone.


Pedometer sensor calculates the number of steps take by the user. But many smartphones using accelerometer data for the Pedometer data, this data is not accurate as the real Pedometer sensor does. Only a few smartphones are equipped with real Pedometer sensor; Google Nexus 5 is one of them.


Global Positioning System also considers as a sensor. A GPS module will connect with satellite and gives you an accurate position result.

Touch Screen

The touch screen of a smartphone is also a kind of sensor which response to human contact. A touch screen is made of multiple layers of glass and works with the pressure of your finger.
