The XZ-L20 senses the amount of light falling on the sensor. That information can be used to determine if something, for example a product, is on top of the sensor if an RFID tag cannot be used. The level of triggering can be set in the controller and the sensor auto-calibrates on startup.†
X-talk
X-Eye Presence pairs easily with any of Nexmosphere's Xperience controllers through the X-talk interface. All functions are programmable in the controller and enable a seamless integration with, for example, Brightsign's media player.
