If you've ever ordered and wire up a 9-DOF sensor, chances are you've also realized the challenge of turning the sensor data from an accelerometer, gyroscope, and magnetometer into actual "3D space orientation"!
This set contains two sensors that are placed in opposite regions to create a monitoring area. If someone goes into this preset area, the sensors will detect this and send a signal to the central system they are part of.
This compact module packs three IR LED/phototransistor pairs onto a 1.25″ × 0.3″ board. The sensors are mounted on a 0.375″ pitch, allowing this array to be used as a minimal detector for a line-following robot. Each sensor provides a separate digital I/O-measurable voltage output.

The QTR-1RC reflectance sensor carries a single infrared LED and phototransistor pair in an inexpensive, tiny 0.5" x 0.3" module that can be mounted almost anywhere and is great for edge detection and line following. See description for more details about the product. Add to cart now!
The module is a high-precision, 24-bit, and communicates with Arduino development plates on a two-wire protocol (clock thread and data thread). More information about the communication protocol can be found in the attached datasheet.
