DFRobot Gravity - line tracking sensor - reflective, digital

Digital sensor of tracking the line, reflective for Arduino, it can detect the white and black lines. Separate signals provides a stable output signal TTL, so it looks for more accurate and more stable line. The sensor is powered with the voltage from 3.3 V to 5 V. The best distance between the sensor and the surface is 1-2 cm.

The sensor is compatible with Arduino, it is connected via 3-pin Gravity connector. Supply voltage is from 3.3 V to 5 V. On the manufacturer's Wiki website, you can find sample code for Arduino.
