AI Overview
A wireless capacitive induction button is a touchless, battery-operated switch used for access control and automatic doors, allowing activation via hand gestures (waving) without physical contact. These devices use capacitive sensing to detect proximity, typically operating on 433MHz frequency with 10–30 meter ranges.
Key Features and Benefits
- Touchless Operation: Reduces germs, ideal for clean environments or handicap access.
