This SmartElex RLS-06 Analog & Digital Line Sensor Array has 6 IR LED/phototransistor pairs, making it a great detector for a line-following robot. It has various other features like potentiometer adjustment for sensitivity, evenly spaced IR transmitters and receivers and 6 sensors for best resolution.
Operating voltage: 4.5V to 5.0 V
Output format: 6 Analog and Digital voltages.
Optimal sensing distance: 0.125″ (3 mm).
Potentiometer to adjust the sensitivity of the individual sensors.
The module is a convenient carrier for six IR emitter and receiver pairs evenly paced.
Great useful in building fast line following and grid navigating robots
Comes with easy to use digital outputs that can be connected directly to microcontrollers
