16-IR-Sensor-Array-using-tcrt5000

A 16 IR Sensor array for Fast Line Follower Bot, I have used the TCRT5000 Reflective Optical Sensor with Transistor Output.

TCRT5000 Reflective Optical Sensor

DESCRIPTION

The TCRT5000 and TCRT5000L are reflective sensors which include an infrared emitter and phototransistor in a leaded package which blocks visible light. The package includes two mounting clips. TCRT5000L is the long lead version.
