To Your Basket Ordering Information Part Number: R185-SINGLE-LINE-IR Price: $14.95 Weight: 0.02 lbs The Single Line Detector, from Lynxmotion, is an infrared reflective sensor, that can be attached to a sumo, or other mobile robot. The sensor delivers a stable TTL compatible high or low voltage depending on the shade of the surface it is positioned over. Use two or more sensors to make a custom line following robot.

More Details:

There is a status LED to make setup or troubleshooting a breeze. The LED is on and the output is LOW when the sensor is positioned over a black or dark surface, or if nothing is there to reflect off of. The LED goes out and the output is HIGH when the sensor is positioned over a white or light surface. The sensor has an 8" connector that can easily plug directly into the digital I/O lines of our BrainStem GP 1.0 microcontroller, the OOPic R microcontroller, as well as various other microcontrollers. The circuitry could also be useful as a surface detector to keep your robot from going off the edge of a table, or tumbling down the stairs. This is a time tested rock solid circuit that will perform flawlessly.

The reflective sensor is made from a one piece Infrared LED and detector pair that are directed at the surface below the front of the robot. There is a built in level comparator with an adjustable reference point so you can fine tune the sensor for different light levels and surface conditions.

Using two or three of these detectors will give you a great line follower!

A manual is included with the sensor.
