4 Channel Infrared Tracking Sensor Module
This module provides a versatile infrared detection system solutions for automation machinery devices such as smart cars, robots. The sensor module is adaptable to ambient light. It has a pair of infrared transmitting and receiving tube. Transmitting tube sends out a certain frequency IR which will be reflected when detecting obstacles (reflecting surface) and received by receiving tube. After processing with comparator circuit, signal output interface outputs digital signal (a low voltage level signal).

Infrared Obstacle Avoidance Sensor Module
IR Infrared Obstacle Avoidance Sensor Module has a pair of infrared transmitting and receiving tubes.
When the transmitted light waves are reflected back, the reflected IR waves will be received by the receiver tube.
The onboard comparator circuitry does the processing and the green indicator LED comes to life.
The module features a 3 wire interface with Vcc, GND and an OUTPUT pin on its tail.
It works fine with 3v3 to 5V levels.
Upon hindrance/reflectance, the output pin gives out a digital signal (a low level signal).
The onboard preset helps to fine tune the range of operation, effective distance range is 2cm to 80cm.

IR Infrared Receiver Photo-diode Receiver 5mm
IR Photo diode is used to detect the light rays reflected from an IR LED. Photo diode is a reverse biased PN junction diode. When photo diode is exposed to light, electrical resistance across the diode decreases there by increasing the reverse current. If the photodiode is not exposed to light, resistance across the will be high .hence reverse current will be extremely small. This current is known as dark current. When light falls on photo diode, electrons acquire sufficient energy to break the covalent bond. Thus free electrons and holes are created. These free electrons will increase the reverse current. Basic circuit of an IR sensor using IR led and IR photo diode is shown below. IR transmitter LED will be emitting IR rays continuously since it’s connected in forward biased state. When an obstacle is present, IR rays from LED gets reflected back and IR receiver will capture these rays. Now IR receiver will conduct, an active low output will be produced.

TCRT5000 Infrared Reflective Switch Line Tracking Sensor
TCRT5000 infrared sensor emits infrared emitting diode continuously when no infrared rays emitted or reflected back is reflected back but the strength is not large enough, the phototransistor has been in the off state, and the output terminal of the module is high, indicating that the diode has been in the off state; in the object to be detected within the detection range, and the intensity of the reflected infrared rays is large enough, phototransistor saturated, and the output terminal of the module is low, the indicator LED is lit.

TCRT5000 Tracking Line Follower Sensor
The TCRT5000 are reflective sensors, which include an infrared emitter and phototransistor in a leaded package, which blocks visible light. The package includes two mounting clips. The Arduino TCRT5000 is designed to sense the distance to an object using Infra Red light waves. It can also identify the difference between white and black based on the contrast of an object and it’s reflective properties.
