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

11. 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.

12. 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.

13. 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.

14. 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.

15. 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.Motorola XOOMSamsung Galaxy Nexus

16. 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.

17. 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. Google Nexus 5

18. 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.

19. 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.iPhone 5sSamsung Galaxy S5HTC One Max

20. 14 different sensors??? From http://www.phonearena.com/news/Did-you-know-how-many-different- kinds-of-sensors-go-inside-a-smartphone_id57885 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!

25. Sensors in phone R:\!SUBJECT AREAS!\ICT\Year 9 database\App Inventor Name of sensorWhat it is used for Advantage of using it Disadvantage of using it Touch screenMeans 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. It measures the room temperature. It can get too hot or cold. TYPE_GYROSCOPE Measures a device's rate of rotation in rad/s around each of the three physical axes (x, y, and z). It rotates your phone to the way you hold it. It can change rotation at the wrong time. TYPE_PROXIMITYMeasures 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. It measures the proximity of an object in cm. You might need to measure it in mm but it only does cm. TYPE_TEMPERATUREMeasures the temperature of the device in degrees Celsius (°C). This sensor implementation varies across devices. It can implementation across other devices. It might go to the wrong devices and then you cannot get it off that device. TYPE_ACCELEROMETER TYPE_LIGHT
