Proximity Detectors

Devices for detecting proximity or presence are options with KIS.

We provide three basic one:

  1. Mat detectors (from Larco). The best and most reliable solution. Has a serial interface and besides being clearly more reliable, it also costs more ($400)
  2. Infrared detectors. See separate page on them. Cost is approximately $150
  3. Ultrasonic. Work very sporadically. We do not recommend them.
