Spread the love

Smartphones are not just about some cool communication features they also accommodate some really amazing sensors inside their body. These sensors enhance users experience by making navigation and many other tasks much more accurate and phone more responsive. With such mobile phone sensors by your side, you can use maps accurately, save battery, track your heartbeat/footsteps, consolidate the security of your device and do lots more.

Through this article let’s find out about these sensors in detail and what their uses are:

Accelerometer: Accelerometer detects the orientation of the phone.

Accelerometer Sensor

USE: When we change the viewing mode from portrait to landscape or opt for auto-rotate, the sensor that detects these changes is an accelerometer. An accelerometer in mobile enables you to view the screen according to the phone’s orientation. You must have noticed that while driving the cursor moves with the car/bike this is also due to this sensor. Accelerometer enables you to navigate with utmost precision, in addition, it can also track your footsteps and tell you how much you have walked in the entire day. It’s a friend that can give you directions in hard times and can also help you stay healthy.

Ambient Temperature Sensor: Ambient temperature sensors can detect the humidity, temperature, and pressure in the environment.

Ambient Temperature Sensor

USE: Gone are the days when smartphones were only used to make calls! Today, with this device you can even save the world! On a serious note, you can manage anything from shopping to paying the bills to weather with this smart gadget. Temperature sensors help you in planning your days, meetings and holidays keeping in view the weather conditions.

Magnetic Field Sensor or Magnetometer or Digital Compass: With the help of magnetic field sensors the phone can sense the directions and can align the screen according to its orientation. With this sensor on, your smartphone is capable of detecting north and south.

Digital Compass Sensor

USE: The sensor is helpful in reading maps and navigation. The phone knows which direction is north and can point right directions even if you alter its orientation. It can also work as a metal detector, one simply needs to install an app and the magnetometer in your phone will start working as a metal detector as the magnets inside the phone will detect the presence of metals around.

Gyroscope Sensor: Gyroscope is often termed as another name for accelerometer because it works as an accelerometer but it’s more precise, and more advanced version of it. It can detect even the smallest turns in the orientation of the phone.

Gyroscope sensor

USE: Gyroscope sensors in mobile phone comes into place when you are navigating using maps, or are running VR apps, watching 360-degree videos or when you are playing games on the phone. This sensor can capture your phone’s position in all three X, Y, and z-axis.  If you often play games in your smartphone then you must be aware that how even the slightest turns can help you maneuver the steering of the car or jump over the hurdles. All these actions are facilitated by Gyroscope sensor.

Heart Rate Sensor: Heart rate sensor reads your heart beats and helps you in tracking your fitness regime. You do not need a sports band or watch to detect that if your phone is enabled with heart rate sensor.

Heart Rate Sensor

USE: You can track your fitness level by analyzing the day to day results from these sensors.

Ambient Light Sensor: The Light sensor in mobile detects the availability of light in the environment and auto adjusts the brightness level.

Ambient Light Sensor

USE: Auto-adjust brightness feature works on this sensor. If you are under direct sunlight and are unable to see the smartphone screen the sensor will increase the brightness level and the moment you come inside under sufficient lighting it will decrease the brightness accordingly. You don’t need to adjust the brightness manually.

Proximity Sensor: Proximity sensor in mobile lies at the front panel of the phone at the top.

Proximity Sensor

USE: It turns off the display when the user is on call in order to save the battery and avoid accidental touch on the screen.

Pressure Sensor or Barometer: Barometer or pressure sensors helps in detecting the weather and finding the altitude one is present at.

Pressure Sensor

Use: You may use it while traveling to find out at what height you are from the sea level.

Biometric Scanners: Biometric scanners include a fingerprint scanner, iris scanner, full-face detection sensors.

USE: These sensors enable the user to strengthen the security of the phone. Only the phone’s owner or authorized people can unlock the phone with their eyes, face or fingerprints.

Biometric Scanners Sensor

Pedometer: It detects how much you have walked the entire day. With the help of this sensor, you can track your physical activity.

Pedometer Sensor

USE: Accelerometer can also detect your footsteps but pedometer is more accurate and is designed specifically to facilitate this task. So, if you are a fitness freak then you must get a phone that comes with this sensor.

So, this is it about the sensors story. Markets are flooded with smartphones that are loaded with dozens of sensors. Now that you are aware of all the sensors that come with a phone and their uses you can wisely choose from the wide range of phones.
