Know Sensors Embedded On Your Smart Phone.

News and Reviews Gadget Technology: smartphone is a mobile phone that has the ability to use and functions that resemble computer. There are a variety of features that are not owned by the mobile phone. This extraordinary ability is usually associated with a fast internet connection, a sophisticated camera, touch screen, GPS, and some equipped with sensors. But do you know the names of the sensor and its use?

This time we will tell you the names sesnsor and utilization.

Sound Sensor
Sound Sensor. Serves to measure the level of intensity of the sound around the smartphone. Helpful when on a call or receive calls in a noisy / crowded, because this sensors will measure the level of sound or noise around it and adjust the volume of the speaker or mic.

Humidity Sensor
Humidity Sensor. Serves to measure relative humidity. Helpful to calculate home humidity, calculate humidity and soil suitable for plant, calculate moisture cage your pet or many others.
Fingerprint Sensor
Fingerprint sensor is a sensor that detects streaks or lines on the finger that provide high security in practicality. Fingerprint sensors are used to unlock the lockscreen, accessing certain applications, unlock, and other commands simply by attaching sensors to the owner's finger. This sensor is used on the Motorola ATRIX 4G smartphone, the Samsung Galaxy S5, the Samsung Galaxy Note 4, iPhone 5S, 5C, 6, 6 Plus, HTC Max; Philips i966 Aurora, Huawei Ascend Mate 7
Gesture Sensor
Gesture Sensor. Its function is to recognize hand gestures to detect infrared light reflected from the user's palm and measure the change in electrical current when the user's finger is in close proximity to the screen. With this sensor, we can make scrolling or other commands on a smartphone with a sweep hand on the screen without touching it.
Heart Rate Sensor
Heart Rate Sensor. Function to count the number of heartbeats. This sensor is on the Galaxy S5 and Galaxy Note 4, the user only needs to press their finger gently against the heart rate sensors located at the bottom of the camera on the back of the smartphone body. With this sensor the user can monitor the physical and health information they supported S-Health applications.

Hall Sensor
Hall sensor. This sensor is intended to detect whether the front cover smartphone accessories (eg: Flip Cover) cover the screen or not. When the cover is closed, then the smartphone screen will change to simple mode (at Samsung, called the S-View mode) which can be seen through the window / glass flip cover.
Pulse Oximetry Sensors
Pulse Oximetry Sensors. Pulse Oximetry Sensor (SpO2) is a sensor that measures the oxygen saturation of the body and measure the amount of oxygen carried by red blood cells. With this SpO2 sensors we can know how effective we breathe and how well the blood is being transported throughout the body. The sensor is only on the Galaxy Note 4.
UV Sensor
UV sensor. UV sensor will work if we are outdoors and under the hot sun. This sensor will measure the intensity of the ultraviolet radiation emitted by the sun. So with this sensor, we can know whether the sun can damage the skin outside (make the skin become darker / irritated) or not.

Accelerometer Sensor
Accelerometer sensor. Serves to identify the accuracy of the direction of a device. The sensor is required in some games like Asphalt, Raging Thunder, etc. Because these sensors we simply tilt the phone when we want to turn right or left

Orientation Sensor
Orientation Sensor. This sensor is used to determine the orientation of the phone and detect the position of the smartphone is in landscape or portrait mode. This sensor is used to rotate the screen automatically.

Proximity Sensor
Proximity Sensor. Serves to detect the presence of an object without physical contact within a certain distance. These sensors play a role when an incoming call. Have you when calling sudden death screen? Yes, that's the work proxity Sensor. When you call, we will of course Android Smartphone is brought to our ears, suppose that the screen is on, then the command menu on the screen can be selected as touched by the cheeks / ears.

Ambient Light Sensor
Ambient Light Sensor. Serves to detect the intensity of light / strong illumination around the smartphone. Play a role in the changing brightness / brightness of the screen. Thanks to this sensor if we are outdoors in the sun, then the screen will automatically increase brightnes full so that the screen remains clearly visible under direct sunlight., If we are in the house / at night, then the screen will decrease brightnessnya to be more power efficient and not dazzle.

Gyroscope Sensor
Gyroscope sensor. Is used to detect and measure the angle of the angular velocity is generally required in navigation. Gyro Sensor somewhat similar to the Accelerometer Sensor. What distinguishes the accelerometer is affected by gravity, while the Gyro Sensor is not affected by gravity. Gyro sensor is able to detect the direction of up, down, left, right, forward, backward, forward and backward pretty gorgeous, rotational motion, roll, pitch, and yaw

Compass Sensor
Compass Sensor. Serves to determine the direction of the wind. Previously you had to install the Compass app in the Play Store first. With the presence of this sensor, then you do not have to worry about getting lost on the way, forests, other areas.

Magnetometer sensor
Magnetometer sensor. Serves to detect the presence of a magnetic field and measuring the magnitude of the magnetic field intensity around the Smartphone. With the presence of this sensor, we can know which of objects emit strong magnetic field, weak, or not.

Barometer Sensor
Barometer sensor. Serves to measure the air pressure. These sensors are needed in navigation, for example you venture into a particular area, then with this sensor, you can know the air pressure in the area you are visiting. This sensor can also predict the weather is going / being good or bad.

Temperature Sensor
Temperature Sensor. As the name implies, this sensor is used to measure the temperature of the temperature smartphone. By knowing the great value of the temperature, we can anticipate our gadgets to avoid damage caused by the temperature is too hot phones. This heat is usually caused by cell phone batteries due to excessive activity of gadgets, such as charging while fumbled the game or surfing fun. In some particular gadget, this sensor can also detect the temperature of the surrounding environment.
