1. General
The XZ Light sensor can detect the amount of light that reaches the sensor. Typically, this value is used to determine whether
an object is picked-up from the sensor, or placed back. This document provides explanation of the available functionalities
and instructions on how to install and integrate the sensor into your digital signage installation.
The information in this document is created for users who are familiar with the Nexmosphere API and are able to control a
basic setup with a Nexmosphere API controller. If this is not the case yet, please read the general documentation on the
Nexmosphere serial API first.

The XZ Light sensor utilizes a Phototransistor which can measure the
amount of light reaching the sensor. The phototransistor is located
on the bottom (flat) side of the sensor.
Typically, the sensor is installed behind a cut-out of a top panel.
On the top panel, objects are placed of which a pick-up or place-back
needs to be detected. When a product is picked-up, light reaches
the phototransistor. When a product is placed back, the cut-out is
covered, blocking the light.
