This T-Slot Photo Interrupter is a simple plastic sensor with two elements - an IR LED and an IR photo-transistor, situated across a U-shaped gap. You can control the IR LED and turn it on to transmit IR light acro...

SKU: SF-SEN-00242 | Brand: SparkFun

The Sharp GP2Y0A21YK is an infrared proximity sensor with an analogue voltage output that varies with distance — from 3.1 V at 10 cm to 0.4 V at 80 cm. It uses an IR emitter and position-sensitive detector to measure ...

SKU: SF-COM-09542 | Brand: SparkFun

The QRE1113 is a small IR reflectance sensor. This sensor is often used in line following robots because, if it can sense if a surface is white or black. There are four pins on the QRE1113 - two control the IR em...

SKU: SF-ROB-09454 | Brand: SparkFun

The SparkFun QRE1113 Line Sensor Breakout (Digital) is a compact IR reflectance sensor board that outputs a digital signal based on surface reflectivity. It uses a capacitor discharge circuit — the faster the 10 nF ca...

SKU: AF-6426 | Brand: Adafruit

The Adafruit STHS34PF80 is a compact IR presence and motion sensor that detects human and animal presence up to 4 metres away — without requiring a lens. Unlike traditional chunky PIR sensors with simple digital outpu...

SKU: AF-1031 | Brand: Adafruit

This SHARP distance sensor bounces IR off objects to determine how far away they are. It returns an analog voltage that can be used to determine how close the nearest object is. Comes with 8" long 3-JST interface wire...

SKU: PL-2454 | Brand: Pololu

The QTR-L-1A reflectance sensor incorporates a right-angle infrared LED and a right-angle phototransistor in an inexpensive, tiny 0.35″ × 0.3″ module that can be mounted almost anywhere and is great for e...

SKU: SF-BOB-09322 | Brand: SparkFun

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 (>...

SKU: AF-164 | Brand: Adafruit

The Sharp GP2Y0A21YK0F is an infrared distance sensor that measures distances from 10 cm to 80 cm by bouncing IR light off objects. It outputs an analogue voltage proportional to distance — approximately 3 V at 10 cm ...
