This analog Line sensor array for line follower robots is based on TCRT-5000 IR sensors and has been designed for Arduino Mega users. It has a total of 10 IR sensors and requires 10 analog pins of a microcontroller or Arduino board (like Arduino Mega).
If you are an Arduino Uno user, you can check out the 6 sensor variant of this sensor array. (click here)
This sensor has got IR LED control option that lets you turn ON and OFF the IR LEDs of the sensor array using a digital pin of Arduino. That ensures unnecessary power consumption when the sensors are not in use. Moreover, the ability to read IR sensors while turning ON and OFF the IR LEDs helps to eliminate the effect of flashlights and sunlight.

1. Best analog line sensor for Arduino Mega. Also compatible with any 5V Arduino board.
2. Supports Pololu QTR library (QTR RA). You can use it just like a Pololu QTR analog sensor.
3. Sunlight and flash resistance. Ability to turn ON & OFF IR LEDs by Arduino digital pin.
4. Small and compact design. Uniform 1cm distance between IR sensors for better line detection.
