The ZX Distance and Gesture Sensor is a touchless sensor that is capable of looking for simple gestures. Developed in conjunction with XYZ Interactive, the sensor uses their GestureSense technology to recognize the distance of an object away from the sensor up to about 10 inches (~25cm) and the location of the object from side to side across the sensor in about a 6 inch (~15cm) span. You will be able to use I2C or UART to communicate with the ZX Sensor via an Arduino-based microcontroller as well as a computer.
On board each ZX Sensor you will find two IR LEDs (inside the brass tubes) and one IR receiver (in the middle). The brass tubes that protect the IR LEDs are actually to block any infrared light going directly from the LEDs to the receiver (we want the light to bounce off an object first). With these IR pieces you will easily be able to ascertain both the Z axis and the X axis of an object (hence the name). In addition to providing Z- and X- axis data about an object, the ZX Sensor is also capable of detecting simple gestures. We have also clearly labeled all the pin outs on the board as well as signifying if they are needed in I2C or UART communication.
Note: Be sure to check out the Hookup Guide for instructions on how to get your ZX Sensor started, load the code and library, and a list of supported gestures.
