This sensor uses an infrared emitted diode combined with an infrared phototransistor to detect the reflected infrared signal. Ideal for sensing black-to-white transitions or can be used to detect nearby objects (.5-1cm).
Photo interrupter, photogate, photodiode, phototransistor, whatever you want to call it, 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 including optical limit switches, pellet dispensing, general object detection, etc. Gap width = 10mm
A breakout board is available.

Use this simple IR receiver for infrared remote control of your next project. With low power consumption and an easy to use package, it mates well with embedded electronics and can be used with common IR remotes.
The TSOP382 is a miniaturized receiver for infrared remote control systems. A PIN diode and a preamplifier are assembled on a lead frame while the epoxy package acts as an IR filter. The demodulated output signal can be directly decoded by a microprocessor. The TSOP382 is compatible with all common IR remote control data formats.
The SparkFun Line Follower Array is a long board consisting of eight IR sensors that have been configured to read as digital bits! We have designed the SparkFun Line Follower Arrays to follow a dark line of about ¾ inch width or smaller (spray paint or electrical tape) on a light background. Each array features visible LEDs that point upward when the board is attached (properly) so you can see what the robot sees, brightness control right on the board, and an I2C interface for reading and power control. Here at SparkFun, the RedBot Shadow Chassis was used as a test platform but really this was..
This version of the QRE1113 breakout board features a digital output, using a capacitor discharge circuit to measure the amount of reflection. This tiny board is perfect for line sensing when only digital I/O is available, and can be used in both 3.3V and 5V systems.
The board’s QRE1113 IR reflectance sensor is comprised of two parts - an IR emitting LED and an IR sensitive phototransistor. When you apply power to the VCC and GND pins the IR LED inside the sensor will illuminate. A 100? resistor is on-board and placed in series with the LED to limit current. The output of the phototransistor..
The Line Follower sensor is an add-on for your RedBot that gives your robot the ability to detect lines or nearby objects. The sensor works by detecting reflected light coming from its own infrared LED. By measuring the amount of reflected infrared light, it can detect transitions from light to dark (lines) or even objects directly in front of it.
The sensor has a 3-pin header which connects directly to the RedBot Mainboard via female to female jumper wires. Use the included RedBot library to detect lines or objects. A mounting hole lets you easily connect one or more of these to the front o..
Knowing where your robot is can be very important! The RedBot Wheel Encoder allows you to track the number of revolutions each wheel has made. This sensor works by detecting the movement of small teeth connected to a motor through the reflection of infrared light. By measuring the amount of reflected infrared light you can tell not only how far each wheel has traveled but how fast the wheels are turning.
The encoder has a 6-pin header which connects directly to the RedBot Mainboard via female to female jumper wires. Use the included RedBot library to start detecting wheel measurments. Two mo..
The SST Liquid Level Sensor provides single point liquid detection via a TTL compatible push/pull output. This optical liquid level sensor features a miniature design that allows for installation in areas where space is limited. Thanks to its minimal solid state design, this sensor has been built without moving or mechanical parts that can be jammed and stop working.
An infra-red LED and phototransistor accurately positioned at the base of the sensing tip ensure good optical coupling between the two when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red light esc..
This is the Vernier Photogate, a new take on the traditional photogate. By emitting a beam of infrared light from one upright to the other, the Photogate can detect when an object passes between the upright gates, breaking the beam. Not only can this Photogate detect objects moving through the interior of itself but also outside by means of a “laser gate”. Simply close a mechanical shutter to block the internal IR gate and shine a laser pen (not included) into the laser gate hole found on the thinner gate arm.
Additionally, the Vernier Photogate can be daisy chained so up to four photogates c..
This is a very small infrared receiver based on the TSOP85 receiver from Vishay. This receiver has all the filtering and 38kHz demodulation built into the unit. Simply point a IR remote at the receiver, hit a button, and you’ll see a stream of 1s and 0s out of the data pin.

A simple breakout PCB for the GP1A57HR photo interrupter (also known as a photogate, photodiode, or phototransistor). 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 (..
The SIS-2 monitors an IR receiver, and when a certain remote code is detected, an output pin will toggle. Two outputs are available and any code on any remote can be taught to the SIS-2. This makes it simple to implement an infrared (IR) remote controllable switching solution for a wide variety of applications. When used with an inexpensive IR receiver module, the SIS-2 recognizes IR signals from 2 independent IR remote control sources, and provides 2 modes of switching for your application.
The IR sources can be from the same or multiple remotes. Works with over 99% of IR remotes, both univ..
Side-looking Infrared Emitters and IR Detectors. These simple devices operate at 940nm and work well for generic IR systems including remote control and touch-less object sensing. Using a simple ADC on any microcontroller will allow variable readings to be collected from the detector. The emitter is driven up to 50mA with a current limiting resistor as with any LED device. The detect is a NPN transistor that is biased by incoming IR light.
