Pololu QTR-3RC Reflectance Sensor Array - 3 IR Channels, Digital squid and projects that need stand-aloneReliable Line and Reflectance Sensing with QTR 3RC Reflectance Sensor Array The QTR 3RC Reflectance Sensor Array is built for line sensing and surface detection in small robots and automation projects. It also works well for edge detection, simple proximity tasks, and reflectance based triggers. Important: Reflectance readings vary with surface color, distance, and ambient light. Best results come from calibrating the sensor over the exact surface and
