10 SMARTPHONE SENSORS EXPLAINED technicalkanu.tech/2019/04/10-smartphone-sensors-explained.html
Friends, we all have an Android smartphone and all of us have been trying their best features. What to say about its build quality, display quality, multimedia, gaming performance and more than camera performance. From Play stores, we keep downloading a lot of applications. But how has our smartphone ever been able to read all the applications and its best features so rigorously? It's the same answer, our Smartphone Sensors. Today's smartphone technology has evolved so much that the kind of sensors we have been experiencing have a great experience. Whenever we think of buying a new smartphone, along with the camera quality, RAM, Storage, and Processors, we should also get information about sensors engaged in that smartphone. Knowing the sensor that we are going to buy a smartphone becomes very important. Because your smartphone is able to do its job properly due to its sensors. So let's know about the best 10 smartphone sensors in this article.
1/6
SMARTPHONE SENSORS # 01: PROXIMITY SENSOR Proximity Sensors plays a very important role in our smartphone. In today's date, almost all smartphones have this sensor. This sensor is mounted on the side of the smartphone ear-piece. Whenever you call someone, as soon as you take the smartphone to your ear, the display of the smartphone stops. Because of this, we avoid any type of accidental touch on the smartphone screen while talking on the call. Whenever we call someone, Proximity sensor leaves a light beam of electromagnetic radiation that does not appear to our eyes. Whenever the light beam hits back with an object, the Proximity sensor closes the Smartphone display. Nowadays there are lots of different types of apps on play stores which use this proximity sensor. Wherever you turn your hands on the screen of the smartphone, it gets locked or unlocked.
SMARTPHONE SENSORS # 02: AMBIENT LIGHT SENSOR Ambient Light Sensor measures light intensity similar to its name. If the light is high, then this 2/6
sensor enhances the smartphone's brightness, and as soon as you go to a less light spot, it automatically reduces that brightness. This technique is also called Auto-Brightness. This sensor is found in every high-end and mid-range smartphone. But some budget smartphones do not have this sensor, so you have to manually control the smartphone's brightness.
SMARTPHONE SENSORS # 03: ACCELEROMETER Accelerometer plays a very important role in our smartphone. This Sensor measures every single movement of the smartphone. As we are watching a video and rotating the smartphone, the orientation of the video automatically rotates. We all know this process as auto-rotate, which is caused by this accelerometer sensor. Along with this, when we play a game in the smartphone, its movements also send the signal to the processor by measuring this sensor. Because of this, we can easily play games by moving the left-right game's smartphone like car racing. This sensor usually happens in all smartphones
SMARTPHONE SENSORS # 04: GYROSCOPE The gyroscope is an advanced version of the Accelerometer. Where accelerometer studies the Xaxis and Y-axis of the smartphone, the same Gyroscope can study Z-Axis along with X-Axis and YAxis. Where the accelerometer is able to detect only Orientation, the same Gyroscope can detect rotation and twist. This gives your Smartphone finely accurate information about which angle you have grabbed your Smartphone. If we get any call in today's smartphones, at that time if the phone is raised from the spot or face-down on the table then the call ring will be muted. In Motorola's smartphones, we see similar 2 gestures. In which if you chop the smartphone twice, then the flashlight is on and the camera app is opened for twisting 2 times. These features are the result of the work of Gyroscope. 3/6
Gyroscope sensor has also become a very important sensor according to the latest technology in today's date. Gyroscope helps us in capturing Virtual Reality Applications (VR) and 360 ° videos. Without Gyroscope, you cannot apply VR mode to your smartphone. These sensors are usually found only in mid-range and high-end smartphones.
SMARTPHONE SENSORS # 05: MAGNETOMETER Magnetometer uses Digital compass. With the help of which your smartphone can study the Earth Magnetic Field. With the help of Magnetometer, you can study north, south, east and west direction. This sensor is used to let us know the direction in Google Maps. Whether we are going in the right direction in the map, this helps us with the help of Magnetometer. In the smartphones that do not have Magnetometer, Google Maps can not work properly at those smartphones, which can cause you to go astray along with this Magnetometer is also a metal detector. If you install a metal detector app on a smartphone, then this magnetometer sensor works for you.
SMARTPHONE SENSORS # 06: BAROMETER The Barometer sensor actually studies your altitude and longitude so that you know the Atmospheric Air Pressure of your location. If you install a weather app, then you will know what your location's Atmospheric Air Pressure is. With this sensor, you can also find out how high you are from the sea level. The barometer works for your GPS sensor. The GPS sensor barometer is used to find your exact location.
SMARTPHONE SENSORS # 07: GPS 4/6
Every Smartphone has a GPS chip. GPS means Global Positioning System GPS sensors send your location signals satellite so that the exact location of your Smartphone is known. Google Maps works with this same GPS sensor. Many people wrongly believe that if our internet data pack is active then this GPS sensor works. So that's not exactly the case. If your internet data pack is not active only then your Google maps application will not work. GPS sensor then does its job even without the internet. Which Mobile Tower is closer to you than the one you are standing on, which can give you more range, this job can not be done without a GPS sensor.
SMARTPHONE SENSORS # 08: BIOMETRIC SENSOR The biometric sensor is usually called a fingerprint scanner. This sensor helps you lock or unlock your Smartphone using your fingerprint. With this advanced level, your Smartphone can do more work through this sensor. Like opening an AAP, navigate menus, drag photos, etc.
SMARTPHONE SENSORS # 09: THERMOMETER By the way, this sensor happens in almost all smartphones. With this sensor, you can measure the internal temperature of your Smartphone. This sensor comes in handy to measure the temperature of your smartphone, as well as the temperature of the CPU and the battery. If the internal temperature is high then the processor gets a signal that the Smartphone has become quite hot. This lets the processor slow down the phone while keeping the components in mind. In today's smartphones, Thermometer sensor also measures the temperature of your surroundings.
SMARTPHONE SENSORS # 10: Pedometer Pedometer Sensor works for us for fitness tracking. This sensor is not something much more important, but if you install a fitness app on your smartphone then your fitness app will not work without this sensor. Thanks to this sensor, you can track how many steps you take in the day. Pedometer Sensor shows your walking distance and step count. With the help of which you can maintain your fitness.
