TCRT5000 IR Barrier Line Track sensor Infrared Reflective Photoelectric Switch
TCRT5000 IR Barrier Line Track sensor Infrared Reflective Photoelectric Switch
This sensor is an Arduino sensor whose connection is compatible with the Arduino sensor extension board. The working principle of the TCRT5000 infrared tube on the sensor is to convert the strength of the reflected signal into a current signal by comparing the different reflectivity of the infrared beam to the color used.
The sensor is active HIGH when black is detected, active LOW when whiteß detected, and the detection height is 0-3 cm. In the circuit, you can use the rotary knob potentiometer to adjust the black and white tracking sensitivity. The sensor has a positioning hole that allows you to attach the sensor to other devices.
