DESCRIPTION

Non-tactile sensors, intuitively easy to use and interactive were designed ad hoc for Kali Interactive Installation. The sensors are highly reliable, not being subject to any electrical contacts, movements, or electromagnetic interference. The sensor working principle is based on infrared beam reflection on human skin. The sensor is an aluminum cylindrical structure, embedding one IR pulsed transmitter, one receiver, and a blue LED. When a finger is placed close to the sensor, IR beams are reflected and detected by receivers. Blue LED switches off to assess the activated state of the sensor.
