 5 Sensors in Smartphones That Can Eliminate the Need to Buy a New Gadget

Modern smartphones are no longer just a means of communication or social networking. The small and invisible sensors inside them have the potential to save you thousands of rupees and replace most external gadgets.

Therefore, before buying a new device, it is necessary to understand the capabilities of the phone in your pocket. Here, we are discussing how the sensors used to make your phone smart work like expensive gadgets.

1. Accelerometer and gyroscope instead of spirit level

Most people buy a 'spirit level' (a device that measures straight lines on the wall) to hang photo frames at home or check whether a drawer is straight. But the 3-axis accelerometer and gyroscope in your phone can easily do this job.

Using apps like 'Physics Toolbox Suite', you can digitally get precise information about the degree of inclination of any surface.

2. Microphone array as an alternative to decibel meter

You no longer need to buy a separate decibel meter to check how loud the noise around you is or whether the volume of your headphones is affecting your ears. The phone's microphone can measure sound with an accuracy of about ±2 dB in the range of 65 to 95 decibels.

This can help you argue with your neighbors about noise pollution or find a quiet place for your children's online classes. Apps like 'Sound Meter' come in handy for this.

3. Magnetometer as a metal detector

Your phone has a magnetometer for finding directions (for a compass). But it also works as a metal detector. This sensor is extremely useful for finding hidden iron pipes or electrical wires before drilling into a wall.

In addition, it can also be used to check the quality of stainless steel, as high-quality steel is usually non-magnetic.

4. Barometer for measuring altitude and weather

Many Android phones have a barometer that measures atmospheric pressure. It increases the accuracy of GPS and also acts as an 'altimeter' (altitude measuring device).

This is very useful for trekkers. Also, fishing enthusiasts can estimate the activity of fish by observing changes in atmospheric pressure. Apps like 'Barometer Plus' help in providing real-time information about local weather.

5. Ambient light sensor instead of lux meter

The ambient light sensor that automatically increases or decreases the brightness of your phone's screen can be used as a 'lux meter'. With the help of apps like Light Meter-Lux Meter, this sensor is useful to check which corner of the room provides the appropriate light when placing a house plant or whether the LED bulb you bought provides the claimed light.

While it doesn't offer the lab-calibrated level of accuracy of professional instruments, it's good enough for comparative measurements.

However, these sensors aren't as precise as professional instruments. For example, a barometer may not give accurate results at altitudes above 3,500 meters, and a magnetometer may not detect small non-magnetic objects.

However, for everyday use, these sensors are extremely reliable and convenient. Experts suggest that it's wise to use these features on your own phone instead of buying unnecessary gadgets and piling them up at home.

Free apps like 'Physics Toolbox Suite' and 'Fifox' can turn your phone into a multi-purpose tool.
