Sensors in a Smartphone and There Uses
Most of us don't know that what the use of sensors in our phone is? Some of the sensors are common in most of the smartphones but some flagship devices comes with advanced sensors. Your phone comes with a lot of gestures. These gestures works with the help of sensors available on your phone. So let us know that how these gestures works with the help of these different sensors. Today I will tell you about these sensors and there uses in detail.
A phone may have sensors from the list below:---
Proximity, Ambient Light, Accelerometer/Gravity, Gyroscope, Fingerprint scanner, Barometer, compass/magnetometer, Infrared Sensor etc.
Q:- What is Proximity Sensor and what is the use of it?
Proximity sensors is used to detect objects in its path. Basically it emits electromagnetic field or infrared beam. If any object comes in path of this beam than it returns back. Hence proximity sensor reacts accordingly.
Range of Proximity sensor in smartphone is maximum 5 cm. When we dial or receive a call, we put phone on our ear. The field is interrupted and proximity sensor turn off the display. When we remove the phone from ear than display automatically turn on. So to turn ON/OFF display automatically while calling proximity sensors are used.
Q:-What is the Use of Infrared Sensor in Mobile? How to use IR blaster?
Now a days IR sensor is also coming to some of the flagship devices. Also some budget phones also have this IR sensor. But most of us don't know the use of it. With the help of IR blaster, your phone becomes universal remote. You can use it to as a remote for your TV, AC, Fridge, DTH Set-top Box, Fan, camera, projector, DVD player etc. If your phone has IR sensor than just go to play store and download any universal remote app.
Q:-What is the use of Ambient Light Sensor?
Ambient light sensors are used to adjust the brightness of smartphone and tablet display. We have to select auto brightness. In bright light display becomes invisible to us, so auto brightness increases the brightness of display so that we can see display clearly.
Q:-What is the use of Accelerometer/Gravity Sensor and Gyroscope?
Accelerometer: With the help of accelerometer phone adjust the orientation of your display. With the help of Accelerometer phone determines the movement and orientation by detecting orientation and vibrations. It uses the simple ball mechanism. Today most of the games are played just tilting the display. This all happens with the help of accelerometer.
Gyroscope: A gyroscope identifies up/down, left/right and rotation or angular rotation around three axes for more complex orientation details. Practically accelerometer helps to find directional movement but Gyroscope/Gyro helps your phone to give perfect orientation by giving lateral orientation of tilt.
Q:-What a Fingerprint Scanner can do?
Now Fingerprint scanner is the most popular feature of a smartphone. Every flagship device is coming with Fingerprint sensor. Basically it is used to unlock your smartphone and secure payment. But in some User interfaces you can also use it to lock your apps, click selfie and pictures and other gestures. This is the most secure method of locking your device but it needs a backup password.
Q;-What is the use of Barometer in smartphone?
You may find your phone features barometer. Most of us thinks that it will check for the weather conditions, but actually it does not do anything with weather. In smartphones barometer is used to help GPS chip. So that device can lock up faster and delivers instant altitude data.
Uses of Compass/ Magnetometer:
Compass is the sensor based on magnetometer. We all know use of a compass. You can check the direction while you are travelling. It also helps GPS map, as it knows the north direction hence your map will shift orientation accordingly.
