Line Tracker Sensor Module HW-006 V1.3
[IR and PIR Sensors] Description The HW-006 V1.3 TCRT5000 IR reflex or line tracker sensor module is based on an infrared reflectance sensor. This is typically mounted at the end of a line that follows the robot chassis. This small tracking sensor module can detect not only transitions from light to dark lines but also objects in front of it. It is ideally used for detecting white or black lines., obstacle detection and meter pulse data sampling. Wiring: VCC: Connect the positive wire of the power supply (5V) GND: Connected to the negative wire of the power supply OUT: High/Low level- Output switching signal SPECIFICATIONS Model/Name HW-006 V1.3 Type Tracker Sensor No of Pin 03 Dimension 35*10*8mm Working Voltage 5V DC Peak Operating Current 20mA to 33mA Output  Digital (0,1) Country of Origin China
TCRT5000 DUAL LINE TRACKING SENSOR MODULE
[IR and PIR Sensors] This IR reflective sensor Module TCRT5000 IR Sensor is used to detect colour and distance. This sensor module consists on an IR transmitter & an IR receiver. IR Transmitter continuously emits IR signal which is then reflected by an obstacle and is then detected by the IR receiver. TCRT5000 Infrared Reflective Sensor Module is often used in line following robots ,object sorting Robot because this module can sense if a surface is white or black. 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.
