The SmartElex RLS-06 Analog & Digital 6 IR Line Sensor Array with Potentiometer is a highly reliable solution for building line-following robots and reflective surface detection systems.
Featuring six pairs of IR LEDs and phototransistors, this IR sensor array delivers both analog and digital sensor outputs for flexible performance.
Each sensor’s sensitivity can be fine-tuned using the onboard potentiometer, ensuring accurate readings under varying surface conditions.
Built around the TCRT5000 reflectance sensor, it offers stable detection of dark and light lines or nearby objects.
The module’s MOSFET-controlled LED design helps minimize power consumption, while its dual-stage resistors enable operation at both 5V and 3.3V.
Compact, efficient, and precise — the SmartElex RLS-06 is ideal for robotics, automation, and DIY electronics applications.
