July Summer Gifts 1-channel Infrared Reflection Tracking Sensor Module Smart Car Black/White Line Detection 3pcs, 3pcs 1-channel Infrared Reflection Tracking Sensor Module Smart Car Black/White Line D

★This module provides a versatile infrared detection system solutions for automation machinery devices ★It uses TCRT5000 infrared reflection sensor whose infrared emitting diodes are constantly emitting infrared rays ★When object is in detecting range, infrared ray will be reflected back with high intensity, the module outputs high level and indicating diode is on ★When the infrared ray emitted is not reflected back or intensity is not high enough, the infrared receiving tube is in the off state and module outputs low level,while indicating diode is off ★Widely used for electricity meter pulse data sampling, fax machine paper detection, obstacle detection, black and white line detection
