Sensors You Have In Your Smartphones?ChecK Out!
In today's modern world, everyone must be using Android phones and it must be having some
sensors such as an accelerometer, gyroscope, proximity and many more. So, today we will be knowing about all such sensors which are used in smartphones and how they work?
Accelerometer
Accelerometers in mobile phones are used to detect the orientation of the phone something that becomes increasingly important with the arrival of augmented reality apps. It also measures linear acceleration of movement which helps in while we are using Maps for travelling. They are also used to provide 'steps' information for a vendors 'health' application.
Gyroscopic Sensor
In addition to the information supplied by the accelerometer, gyroscope by tracks rotation or twist.It measures the angular rotational velocity.
Practically an accelerometer will measure the directional movement of a device but will not be able to resolve its lateral orientation or tilt during that movement accurately unless a gyro is there to fill in that info.
Magnetometer(Magnetic Field Sensor)
A magnetometer measures magnetic fields and can thus tell you which way is north by varying its voltage output to the phone. When you go in and out of compass mode in Apple Maps or Google Maps, that’s the magnetometer kicking into work out which way up the map should be. It also powers standalone compass apps.
Proximity Sensor
Detects when an object is near to the phone. Most commonly used to sense when a phone is held up to the user's ear to turn off the display. This saves both battery life and prevents accidental screen touches.
Ambient Temperature and Light Sensor
This sensor provides the ambient (room) temperature in degrees Celsius and light sensor takes a measure of the light in the room and adjusts your screen’s brightness accordingly (if indeed it’s set to auto-adjust).
Barometer
Barometer measures air pressure and also useful for detecting weather changes and calculating the altitude you’re at.
Heart Rate
A heart rate sensor reports the current heart rate of the person touching the device.
