THE ROLE OF SENSORS IN MODERN TECHNOLOGY
Sensors play an important role in modern technology by helping devices collect information
from their surroundings and make smart decisions. Below are some key areas where
sensors are transforming technology.
Making Apps Easy to Use
Sensors help make apps more fun and interactive. The Accelerometer Sensor helps
control games by moving the phone. The Proximity Sensor turns off the screen when you
bring the phone close to your ear during a call.
Helping with Maps and Fitness
Sensors help people find their way and stay healthy. The GPS Sensor shows your real-
time location on a map. The Pedometer Sensor counts your steps when you walk or run,
helping you track your fitness.
Making Homes and Devices Smarter
Sensors make devices work automatically. The Light Sensor adjusts screen brightness
depending on the light around you. The Near Field Communication Sensor allows
contactless payments, making shopping easier and safer.
Keeping Things Safe and Secure
Sensors help protect information and secure devices. The Fingerprint Sensor locks and
unlocks phones. The Barcode Scanner is used to scan QR codes for payments and security
checks.
Helping Scientists and Businesses
Sensors collect important information. Environmental Sensors check air quality and
temperature. The Gyroscope and Orientation Sensors help in virtual reality (VR) games
and apps.
PEDOMETER APP
A Pedometer App is an application that counts the number of steps a user takes while
walking or running. It uses a Pedometer Sensor to track movement and display the step
count on the screen.
