Sensors From http://www.bbc.co.uk/guides/zss3gk7

Sensors gyroscope The gyroscope is a sensor that can provide orientation information as well, but with greater precision. Thanks to this particular sensor, Android's Photo Sphere camera feature can tell how much a phone has been rotated and in which direction. It is also used by Google's Sky Map for telling what constellation you're pointing a phone at.

Sensors magnetometer. Another sensor that most (if not all) smartphones now have is the magnetometer. Yup, it is able to detect magnetic fields. The magnetometer is one of the sensors that compass applications use to point at the planet's north pole. Apps made to detect metal use this sensor as well.

Sensors proximity Next up we have the proximity sensor, which is comprised of an infrared LED and an IR light detector. It is placed near the earpiece of a phone, and for a good reason – when you place the handset up to your ear, the sensor lets the system know that you're most probably in a call and that the screen has to be turned off. The sensor works by shining a beam of invisible to humans infrared light which is reflected from a nearby object and picked up by the IR detector.

Sensor light A phone's light sensor is what measures how bright the ambient light is. The phone's software uses this data to adjust the display's brightness automatically – when ambient light is plentiful, the screen's brightness is pumped up, and when it is dark, the display is dimmed down. An interesting fact is that high-end Samsung Galaxy phones use an advanced light sensor that can measure white, red, green, and blue light independently. And that's not overkill. In fact, the Adapt Display feature uses this data to fine tune image representation.

Sensors barometer Higher-end phones have a built-in barometer – a sensor that can measure atmospheric pressure. Data measured by it is used to determine how high the device is above sea level, which in turn results in improved GPS accuracy. On a related note, the Motorola XOOM and the Samsung Galaxy Nexus were among the first Android devices to feature this sensor.

Sensor Thermometer thermometer for measuring ambient temperature. However, there's a thermometer in pretty much any smartphone, and some handsets might have more than one of them. The difference is that they're used to monitor the temperature inside the device and its battery. If a component is detected to be overheating, the system shuts itself down to prevent damage. And speaking of the Galaxy S4, it pioneered the use of an air humidity sensor in a smartphone. Data provided by it was used in the S Health application to tell whether or not the user was in their "Comfort Zone" – one with optimal air temperature and humidity.

Sensor Pedometer While we're at the health and fitness topic, the pedometer is a sensor used for counting the number of steps that the user has taken. Such data is usually obtained by the device's accelerometer, but a dedicated pedometer is a lot more accurate and power efficient. The Google Nexus 5 is among the few phones that have a true pedometer built into them.

Heart rate monitor This list would be incomplete if we do not mention the heart rate monitor on the Galaxy S5. As you can tell, it is made to measure one's pulse, and it does that by detecting the minute pulsations of the blood vessels inside one's finger.

Sensors fingerprint We must also mention the fingerprint sensors built into a number of smartphones, including the iPhone 5s, the Samsung Galaxy S5, and the HTC One Max. Of these, the 5s has the sensor most convenient to use as it does not require swiping in order to read fingerprint data. Fingerprint scanners are most often used as an extra layer of security – as a substitute for a lock screen password.

14 different sensors. From http://www. phonearena Adding the microphone and the cameras to the list gives us a figure of at least 14 different sensors that are (or have been) used in a smartphone. That's quite a lot of data that a smartphone can pick up, use, and provide. And with smartphones getting more and more awesome by the year, the list is surely to keep on growing. Think there's a sensor that we've missed? Let us know down in the comments!

Sensors Sensor Type Description Common Uses TYPE_ACCELEROMETER Hardware Measures the acceleration force in m/s2 that is applied to a device on all three physical axes (x, y, and z), including the force of gravity. Motion detection (shake, tilt, etc.). TYPE_AMBIENT_TEMPERATURE Measures the ambient room temperature in degrees Celsius (°C). See note below. Monitoring air temperatures. TYPE_GRAVITY Software or Hardware Measures the force of gravity in m/s2 that is applied to a device on all three physical axes (x, y, z). TYPE_GYROSCOPE Measures a device's rate of rotation in rad/s around each of the three physical axes (x, y, and z). Rotation detection (spin, turn, etc.). TYPE_LIGHT Measures the ambient light level (illumination) in lx. Controlling screen brightness. TYPE_LINEAR_ACCELERATION Measures the acceleration force in m/s2 that is applied to a device on all three physical axes (x, y, and z), excluding the force of gravity. Monitoring acceleration along a single axis.

Sensors TYPE_MAGNETIC_FIELD Hardware Measures the ambient geomagnetic field for all three physical axes (x, y, z) in μT. Creating a compass. TYPE_ORIENTATION Software Measures degrees of rotation that a device makes around all three physical axes (x, y, z). As of API level 3 you can obtain the inclination matrix and rotation matrix for a device by using the gravity sensor and the geomagnetic field sensor in conjunction with the getRotationMatrix() method. Determining device position. TYPE_PRESSURE Measures the ambient air pressure in hPa or mbar. Monitoring air pressure changes. TYPE_PROXIMITY Measures the proximity of an object in cm relative to the view screen of a device. This sensor is typically used to determine whether a handset is being held up to a person's ear. Phone position during a call. TYPE_RELATIVE_HUMIDITY Measures the relative ambient humidity in percent (%). Monitoring dewpoint, absolute, and relative humidity. TYPE_ROTATION_VECTOR Software or Hardware Measures the orientation of a device by providing the three elements of the device's rotation vector. Motion detection and rotation detection. TYPE_TEMPERATURE Measures the temperature of the device in degrees Celsius (°C). This sensor implementation varies across devices and this sensor was replaced with the TYPE_AMBIENT_TEMPERATURE sensor in API Level 14 Monitoring temperatures.

Disadvantage of using it Name of sensor What it is used for Advantage of using it Disadvantage of using it Touch screen Means you can control the screen with your finger or pen type instrument Intuitive to use. Quicker to access information when using this type of device Need a conductive and resistive layer under the screen which means only 75% of the screen light will get through TYPE_AMBIENT_TEMPERATURE Measures the ambient room temperature in degrees Celsius (°C). See note below. If the temperature gets to high or low then it can warm people to that they wouldn’t die. TYPE_GYROSCOPE Measures a device's rate of rotation in rad/s around each of the three physical axes (x, y, and z). The screen tips the way that a phone is turning so that you can see the screen better or makes the screen wider. TYPE_PROXIMITY Measures the proximity of an object in cm relative to the view screen of a device. This sensor is typically used to determine whether a handset is being held up to a person's ear. Its good because it saves your battery whist your on the phone. TYPE_TEMPERATURE Measures the temperature of the device in degrees Celsius (°C). This sensor implementation varies across devices and this sensor was replaced with the TYPE_AMBIENT_TEMPERATURE sensor in API Level 14. Because it can worn old age and people that is either too hot or too cold. TYPE_ACCELEROMETER Measures the acceleration force in m/s2 that is applied to a device on all three physical axes (x, y, and z), including the force of gravity. Good because it can tell you how fast you are going, during when your driving. TYPE_LIGHT Measures the ambient light level (illumination) in lx. Saves the battery in light and dark rooms, as it changes to room darkness.
