The measuring distance range from 1mm to 8mm, and the central point is about 2.5mm. There is also an on-board potentiometer to adjust the sensitivity. The infrared diode will emitting the infrared continually when the module is powered ON, when the emitted infrared light has not been reflected or the strength is not big enough, the receiver diode will in the off state and output pin i.e. DO will be LOW. Description of Line Tracking sensor TCRT5000L:- Main chip: LM393, Designed with reflected infrared sensor, indicator light. Built in a potentiometer for sensitivity control. On-board LM393 voltage comparator chip and infrared sensing probe TCRT5000L Support 5 V / 3.5 V voltage input On-board signal output instructions, output is high effective signal at the same time, the indicator lamp light output signal can be directly and single-chip microcomputer IO connection & mid dot; Signal detection sensitivity can adjust Reserve all the way more circuits (P3 voltage drawn) using TCRT5000 infrared reflection sensor test reflection distance: 1 mm to 25 mm Operation voltage: 3.5v-5V Operation current: >15mA wide voltage LM393 comparator output form: digital switch output (0 and 1) a fixed bolt hole, convenient installation.
