ZX Distance and Gesture Sensor SMD Hookup
Guide
Introduction
The ZX Distance and Gesture Sensor is a collaboration product with XYZ
Interactive. The innovative people at XYZ Interactive have created a unique
technology that allows for simple infrared (IR) beams to be used to detect
an object's location in two dimensions.
The ZX Sensor is a touchless sensor that is capable of looking for simple
gestures in the air above the sensor (e.g. swipe left or swipe right).
Additionally, the sensor can also recognize the distance of an object away
from the sensor at distances up to about 12 inches (30 cm), referred to as
the "Z" axis, and the location of the object from side to side across the
sensor in about a 6 inch (15 cm) span, referred to as the "X" axis.

 SE N-1316 2
Covered in This Tutorial
We can use I C or UART to communicate with the ZX Sensor. In this
2
tutorial, we will show you how to connect the sensor to an Arduino or
Arduino-compatible board as well as a computer so you can start creating
gestures to handle all our your daily tasks or add some interactive flair to
your project.
