This magnetometer sensor is employed as a compass within smartphones and this sensor is employed for detector apps within mobile phones. A magnetometer is just like a magnet and it can attract the opposite magnets and sense the magnetic materials and applications within mobile phones.
5. Ambient light sensor
This Ambient light sensor is usually referred to as the Auto brightness sensor. This light sensor adjusts the brightness of the mobile screen in accordance with the atmosphere light.
The ambient light sensor is extremely helpful to us and it automatically adjusts the screen brightness with reference to the change in atmospheric light. This will help us to scale back the over brightness and under brightness of the screen. And this will also reduce the effect of the brightness of the screen on human eyes.
6. Barometer sensor
This Barometer sensor is employed for measuring the air pressure and this barometer sensor is employed in Mobile’s for locating the weather within the local area using the GPS.
The barometer sensor gives precise information about the altitude of our mobile device to GPS to seek out the precise weather conditions at that place. This will even be helpful to seek out the weather thereon day and therefore the next 10 days with some minor changes.
7. Thermometer sensor
The thermometer is extremely documented to all or any folks and this is often wont to find the temperature, similarly, this thermometer sensor is employed to seek out the temperature of the smartphones, for both internal and external temperatures.
This can be used for locating the outer temperature on the backside or front side of the mobile and for locating the temperature range of internal parts like processor, battery, and CPU temperatures by using this thermometer sensor.
8. Air Humidity sensor
Air Humidity sensors tell us the quantity of Humidity present within the air within the atmosphere. Atmospheric air mainly consists of nitrogen gas, oxygen gas, CO2 gas, and a few water molecules.
Generally, we use smartphones within the atmosphere but sometimes within the air, we’ve excess humidity or water content. At that point, this sensor was useful to us. When there’s excess Humidity within the air sometimes our phones could also be damaged.
9. Heart rate sensor
A heart rate sensor is employed for locating the guts rate of humans by placing their fingers on this sensor for one minute. It’ll give information about the guts rate of that person.
The pulse sensor is extremely helpful to the aged people for locating their pulse or pulse if there’s any difference within the normal pulse of the person and this sensor can alert the user to consult a doctor immediately. This pulse sensor is especially utilized in fitness trackers and smartwatches and also on some mobile phones.
10. Pedometer sensor
Pedometer sensors are used for the step count of humans. We will estimate the number of walking steps during the day. This will also give the knowledge of our daily exercise or walking steps and this sensor is additionally used mainly in fitness trackers and smartwatches and a few mobile phones.
11. Blood oxygen sensor
This Blood oxygen sensor gives the quantity of oxygen present in our blood. Our blood contains mainly oxygen, blood cells, water, and iron, etc. to seek out the quantity of oxygen present in our blood. We are using this blood oxygen sensor. A blood oxygen sensor is especially seen in high-end mobiles.
12. HAL sensor
This HAL sensor is employed for sensings like proximity sensing, current sensing, positioning, and speed detection in smartphones. The HAL sensor isn’t much utilized these days but we’ve some great uses with this HAL sensor like sensing the Speed, current and position of the thing, etc.
13. UV sensor
These UV sensors are wont to find the UV rays from the sun that are present within the atmosphere. Ultraviolet rays coming from the sun onto the surface and these UV rays are very harmful to the citizenry and cause many diseases and side effects to the living creatures. For locating the UV rays we are using the UV sensor within the mobile phones.
14. Fingerprint sensor
This fingerprint sensor or touch ID is common on every smartphone. This fingerprint scanner is for security purposes and this sensor becomes a neighborhood of our mobile. The fingerprint scanner is at the rear of the mobile or optical In-display fingerprint on the screen.
