Mobile Phone Sensors – Types of Sensors in Smartphone
List of Different Types of Sensors in Android Smartphone and Apple iPhone and their Function.
Mobile Phone Sensors are of Different Types for different functions that make it Smartphone. Although there are Different Types of Sensors in a Smartphone, Here I will focus only on the Major and Most Important ones and their Function.
Different Types of Mobile Phone Sensors and their Function
Accelerometer
The Accelerometer Sensor in a Smartphone (Both Android and Apple iPhone) can detect Tilt or Orientation of the Phone. It can also detect Vibration and Acceleration. It is basically this Sensor that helps to determine whether the phone is in portrait or landscape orientation.
This sensor can also detect if the display of the phone is in upward or downward position. It also detects movement of the phone in any given direction.
Air Humidity Sensors
This sensor is not very popular at present but it will surely be used by more and more Popular Mobile Phone Brands in the near Future. As the name suggests, this sensor can measure humidity in air. This data can be used in several useful ways.
Ambient Light Sensors
As the name suggests, this Sensor detects the Light or Brightness to automatically adjust Brightness of the Display. It is used when we put of Phone in Auto Brightness Mode.
Barcode / QR Code Sensors
These Sensors can read Barcodes on Product Packaging and QR Codes. Most modern smartphone manufacturers install this Sensor.
Barometer
This sensor can measure Air Pressure that can be useful in several ways such as studying Weather and Altitude Change. Only High-End and Expensive Phones have these Sensors.
Fingerprint Sensors
The Fingerprint Sensor has become very common in most modern mobile phones. It is generally found at the back of the Smartphone and sometimes in the front bottom. Some manufacturers have also started to install it in-display itself.
The Fingerprint sensor can read and store biometric data of our fingers and can be used to unlock the phone thus replacing the use of any password or pattern.
GPS
GPS or Global Positioning System is also very common and popular is most modern phones. It helps to locate location on Earth and helps in Navigation.
Popular Services like Ola, Uber, Zomato and Swiggy use GPS Feature.
Gyroscope
The Gyroscope can detect orientation, rotation and direction of the phone very precisely. Many popular gaming apps use these feature of the gyroscope sensor.
Hall Sensor
The Hall sensor can detect magnetic field. This feature is used to Sleep and Wake the Phone when a Flip Cover is used.
Magnetometer
The Magnetometer is what acts as the compass in our Smartphone. This sensor detects magnetic field and can easily determine the direction of the North Pole. It can also detect metal.
Therefore the Magnetometer is used in Maps, Compass, Navigation Apps and Metal detector apps.
Proximity Sensor
The proximity sensor can detect distance of the phone from our skin or any other object. This feature is used to disable the Touchscreen when we receive a Phone Call and the phone is held near our Ear.
Thermometer
The thermometer in a Smartphone monitors temperature of the device and the battery. It is used to display the Temperature of the device and Environment. It is also used to shutdown the device in case of Overheating to prevent any damage.
Touchscreen Sensors
The Touchscreen sensor is used to input data in the phone.

Sensors in Smartphone FAQs
What is an accelerometer in a smartphone?
An accelerometer in a smartphone is a type of sensor that measures the phone's orientation and movement. This sensor is commonly used to adjust the orientation of the phone's screen when it is rotated, and to enable features such as shaking the phone to undo or redo an action.
What is a gyroscope in a smartphone?
A gyroscope in a smartphone is a type of sensor that measures the phone's rotation and angular velocity. This sensor is commonly used in conjunction with the accelerometer to enable features such as augmented reality apps, which require precise tracking of the phone's movement.
What is a fingerprint sensor in a smartphone?
A fingerprint sensor in a smartphone is a type of sensor that allows users to unlock their phone and authenticate purchases or logins by scanning their fingerprint. This sensor is commonly located on the back or front of the phone, and uses advanced algorithms to create a unique digital representation of the user's fingerprint.
What is a light sensor in a smartphone?
A light sensor in a smartphone is a type of sensor that detects the ambient light level in the phone's surroundings. This sensor is commonly used to adjust the brightness of the phone's screen automatically, depending on the lighting conditions. It can also be used to detect when the phone is in a pocket or bag and turn off the screen to save battery life.
