In electronic components, proximity refers to a proximity sensor.
Proximity sensors are commonly used to detect and measure when an object or person is nearby.
Proximity sensors can operate on a variety of principles, most notably infrared (IR) sensors, ultrasonic sensors, and capacitive sensors.
These sensors are widely used in electronic components and are utilized in various fields such as mobile phones, automobiles, and robots.
For example, a smartphone's proximity sensor turns off the screen while the user is looking at it, turns it back on when the user leaves the screen, and so on.
In cars, it is used to measure the distance to the vehicle in front while driving, and in robots, it is used for environmental awareness and obstacle avoidance.
