- Innovative Light Sensing Technology
Say goodbye to contact. Prevent cross-propagation of bacteria. Using light-sensitive modulation and demodulation. No interface and disturbed signals, Non-contact induction by hand(or reflective object).
- The distance between the finger and the button can be sensed within 2 – 4cm, the blue light will be illuminated immediately after the induction is successful, indicating that the elevator is waiting.
