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 IDs as 20 (unsoldered plug) and 22 (soldered plug) andrew xyzinteractive.com CONFIDENTIALXYZ Interactive Technologies Inc. Page 1The ZX/SP sensor has labeled connections with UART and I2C separated. This makes it easy to connect ready-made connectors (like the FTDI UART connector) directly to the ZX sensor pins (as shown). Similarly, the I2C connection pins may connect to any two-wire interface using the ZX sensor as the I2C slave, and any embedded or external processor as the I2C master. andrew xyzinteractive.com CONFIDENTIALXYZ Interactive Technologies Inc.
