In a world increasingly driven by hygiene, convenience, and smart technology, touchless sensing has emerged as a powerful innovation. From smartphones to smart homes and public kiosks, the ability to interact with devices without physical contact is transforming how we live, work, and communicate.

What is Touchless Sensing?
Touchless sensing refers to technology that detects and responds to physical gestures, presence, or motion without direct physical contact. These systems rely on various sensors—like infrared, ultrasonic, capacitive, or cameras—to interpret hand gestures, body movements, or even facial expressions.

Key Technologies in Touchless Sensing
Infrared Sensors – Detect heat or motion, commonly used in automatic doors and soap dispensers.

Ultrasonic Sensors – Measure distance through sound waves, often used in parking systems and gesture recognition.

Capacitive Sensors – Sense the proximity of a finger or hand, enabling hover-based control.

Optical and Camera-Based Systems – Use computer vision and AI to track complex gestures or facial cues.

Radar-Based Sensors – Compact and highly accurate, used in mobile devices and automotive applications.
