What is a Proximity sensor?

A proximity sensor detects the presence or approach of an object within a certain range without physical contact. It operates based on principles like magnetic fields, electromagnetic waves, ultrasonic waves, or infrared radiation. Its non-contact nature ensures durability and resistance to wear. Common industrial applications include position detection of machinery and collision avoidance. In automobiles, it is used for obstacle detection and parking assistance. Additionally, it is widely utilized in smartphones and home appliances to optimize user interaction.

Application of Proximity sensor

✅ Factory Automation
Detects object positions on production lines to control robotic movements.
✅ Vehicle Collision Avoidance
Sensors in cars detect obstacles to assist with emergency braking.
✅ Smartphones
Detects proximity of the user’s face or hand to turn off the screen and save battery.
✅ Home Appliances
Supports gesture control to turn lights on/off or operate devices.
