Line Follower Sensor (Adjustable)
$1.99  
Out-of-stock
The Line Follower sensor gives your robot the ability to detect lines or nearby objects. The sensor works by detecting reflected light coming from its own infrared LED. It can detect transitions from light to dark (lines) or even objects directly in front of it. The sensor has an...

Photo Interrupter GP1A57HRJ00F
$4.00 $5.55  
3 pc(s)
This sensor is composed of an infrared emitter on one upright and a shielded infrared detector on the other. By emitting a beam of infrared light from one upright to the other, the sensor can detect when an object passes between the uprights, breaking the beam. Used for many applications...

Photo Interrupter GP1A57HRJ00F Breakout Board
$2.35  
4 pc(s)
A simple breakout PCB for the GP1A57HR photo interrupter. This PCB has three connections for PWR, GND, and Signal. When the gate is clear, SIG will be high (>4.9V). When the gate is blocked by a finger, writing utensil, food pellet, or anything else - SIG will go low (<0.4V)....

Photo Interrupter Module (Straight)
$2.50  
6 pc(s)
This Photo Interrupter Module is widely used in motor speed detection, pulse count, the position limit, etc. It will trigger a signal when light between the sensor's gap is blocked. It works with 3.3V to 5VDC, and gives a HIGH on DO pin when the beam is blocked, and a LOW output when...

QTR-8A Reflectance Sensor Array
$15.00  
1 pc(s)
The QTR-8A reflectance sensor array is intended as a line sensor, but it can be used as a general-purpose proximity or reflectance sensor. The module is a convenient carrier for eight IR emitter and receiver (phototransistor) pairs evenly spaced at intervals of 0.375" (9.525 mm). Each...

Through-Beam Infrared Sensor Kit - 30cm
$7.90  
8 pc(s)
This Through-Beam Infrared Sensor Kit consists of two separate components: an Infrared transmitter and detector. They work by having an transmitter side that sends out a beam of human-invisible infrared light, then a detector across the way which is sensitive to that same light. When an...
