TCRT5000 BASED IR LINE FOLLOWING SENSOR
This IR reflective sensor utilizes a TCRT5000 to detect color and distance. It emits IR rays and then detects if it receives the reflection.
This sensor is often used in line following robots, auto data logging on utility meters, because this module can sense white or black surface
The measuring distance range is from 1mm to 8mm . There is also an on-board potentiometer to adjust the sensitivity.
The infrared diode emits the infrared ray continuously when connected to power
When the emitted infrared light has not been reflected or the strength is not big enough, it will be in the off state, at this time, D0 output logic is LOW and the signal indicates LED off.
Supply Voltage: 3.3V~5V
Detection distance: 1mm - 8mm
Digital Outputs HIGH when an object is detected
On-board indicator LED to show the results
On-board potentiometer to adjust the sensitivity
On-board LM393 chip
Usually used for line following robot
