The Single Line Detector 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. 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 plug directly into our Bot Board. 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.
