XYZ Interactive Technologies, ZX SparkFun Sensor Datasheet
Introduction
XYZ Interactive Technologies (in conjunction with SparkFun Electronics Inc.) has developed introductory
ZX Sensor Models that can be used for rapid proof of concept or for sensor related applications.
These sensors consist of two transmitter(s) and one receiver mounted on one board that constitutes a
short-range reflective distance measurement solution. Current design utilizes infrared technology.
The sensor may be preprogrammed to operate as a ranging device or as a gesture interface. The
package includes a sensor, a USB to serial board, Mini-B USB cable, and downloadable serial software.
The user can demonstrate simple position detection, distance measurement and basic gestures within
minutes of opening the package.
This sensor includes a UART for demo applications and I2C as a communication protocol for embedded
applications like robotics and toys, or devices that have to communicate directly to a processor.
ZX Sensor
The following describes the ZX sensor. There are two types of the ZX sensor available (as shown). The
ZX sensor is available as versions with 1) Through-Hole parts (TH ZX sensor) which allows sensing
solutions that have longer range because of lensing on the emitter snd receiver, and 2) SMT parts (SMT
ZX sensor) which allows sensing solutions that are more compact and may be hidden under IR
transmissible plastic.
The ZX sensor is designed with the following characteristics:
1. UART at 115200 baud (see UART details below)
2. I2C interface (see I2C details below)
3. Continuous data output at a rate of 50 samples/sec
4. Simultaneous UART/I2C data output
5. 3D object detection in depth and in the periphery
6. On-board gesture detection and output (swipes, hand-push, etc.)
7. Optional on-board pull-down resistors for I2C
8. Support for up to two ZX sensors on one I2C bus
9. Optional I2C ID’s as 20 (unsoldered plug) and 22 (soldered plug)
