Types Of Sensors in our Phones !

Since the evolvement of SmartPhones, there has always been hype about various types of sensors that are embedded within them to extend the functionality and productivity of SmartPhones. So before I get into the various types, I guess it's my duty to first tell you guys What actually Sensors are: So yes, We can describe sensors as a device which detects or measures a physical property, records it or indicate something or provide some functionality that has been programmed according to the recorded property. Confused? No worries, just read the article below and your every confusion will fade away.

What are the Various Types Of Sensors in Our Phones?

• Accelerometer: What it does it tells the software of our phone that how we are holding our phone, like Auto-Rotate feature, when we enable the auto-rotate feature on our phone and we are watching some picture or videos then if we are holding our phone in landscape mode the same will change in landscape mode and when in portrait the same will come in portrait mode. Some of the phone's accelerometer is also responsible for switching the phone in power saving mode when we put it upside down and also if a phone call is coming and we are flipping the phone, it will get into the silent mode.Thus accelerometer tells the software of our phone that how we are holding our phone and what functionality it has to perform in this situation.


• Gyroscope/GyroSensor: It is like the accelerometer but it tells the software the information more precisely like it will tell that at what angle we are holding our phone at which degree it is tilted. 360-degree photos and videos require it and in some games, it is also used in various games and in tells the software or the app which functionality has to be performed according to the holding angle.For example, if we are watching 360-degree videos of roller coaster ride on YouTube and if our phone is containing Gyrosensor then by surely moving our phone in a different-different angle we can really get the excitement and feel of the ride by sitting at home.


• Magnetometer: It works as a compass in our phone, if it is not in our phone then we won't be able to see directions in maps and navigations, it is also gets implemented in metal detector apps.It detects whether some metal is kept near the phone and tell us which metal it is.


• Proximity Sensor: We can see proximity sensor somewhere around the front camera or nearby ear piece, it is used to measure the distance between our phone screen and us, like when we are on call it turns off the screen to prevent the unwanted clicks of buttons and also preserves battery resources.Mainly used in Motorola phones, like when we move our hand over the screen the screen gets turned off or notifications get shown up.Proximity sensor throws Infrared and checks that whether infrared came back or not and based on it measure the distance and find out whether there is something nearby our phone or not.


• Light Sensor/Ambient Light Sensor: Maintains the screen brightness based on the light available around.For example, if we are using our phone in sunlight so it is sure we need higher brightness for better visibility, Light Sensor will increase the brightness for us, and if we are using our phone at night then it will lighten up the screen brightness for the sake of our eyes and pleasant display.


• Barometer: It measures atmospheric pressure to tell us how much above we are from the sea level, it helps GPS to find out the location more accurately, also implemented in health-related apps to tell us that how much we went up the hill or came down the hill.


• Thermometer: We all know what Thermometer does it measures temperature right, In some phones, internal thermometer sensors are there, By them Internal temperature measurement is done, CPU temperature or battery temperature is measured and if they are higher then their specifications then it will report to the software to calm them down to their actual temperatures. In some phones, External Thermometer is also there like in Samsung Galaxy S4 and S5.


• Air Humidity Sensor: This sensor measure the humidity in the Environment.


• Pedometer: Pedometer is found in some of the phones, it basically tells us precisely about the steps that we have walked today. It is basically gets implemented in health-related apps.


• FingerPrint Sensor:  This is the highly popular and highly used sensor nowadays, as a number of smartphones that are entering the market these days are coming with it and provide features like fingerprint lock unlock and for the authentication purpose it can be also used for application purchase.


• There is another sensor which is currently getting used in Japanese phones only named as Radiation Sensor that measures the harmful radiation present in the Environment.

I hope now you guys are clear about the various types of sensors and their usage in your phones, these sensors presence depends on according to different mobile phone companies it is completely up to them that which sensors they want to embed in their phones.
