SKU: AF-2168

Infrared (IR) break-beam sensors are a simple way to detect motion. They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way which is sensitive to that same light. When something passes between the two, and its not transparent to IR,...

SKU: AF-5069

The Adafruit FunHouse Starter Kit gives you everything you need to build WiFi-connected home automation projects with no soldering required. Powered by an ESP32-S2 chip running CircuitPython or Arduino, the FunHouse board connects to your WiFi network and makes it easy to create internet-powered ...

SKU: AF-5940 · MPN: ADA5940

This breakout uses Vishay's TSSP77038 infrared demodulator to give you the raw demodulated output from a 38kHz IR signal, without the extra filtering used in typical remote-control receivers. That makes it a handy choice for reflective sensing, light barriers, fast proximity detection, and modula...

SKU: AF-3930

This Reflective IR Sensor is a simple plastic casing with two elements - an IR LED and an IR phototransistor. You can control the IR LED and turn it on to bounce IR off objects to determine their reflectivity. White & light colored stuff will bounce the light, so  you can detect it. Black...

SKU: LB-LR0309-6

A matched pair of 5mm infrared LEDs — one transmitter (clear) and one receiver (black) — operating at 940nm. Use them to build object sensors, colour sensors, line sensors, distance sensors, and custom wheel encoders. Specifications Size – 5mm Lead Length – 37mm Wavelength – 940nm (infrared)...

SKU: DF-SEN0503

An infrared break-beam sensor pair for simple, reliable motion detection. The emitter sends a beam of invisible IR light to the receiver — when an object passes between them and breaks the beam, the receiver outputs a signal. Works up to 50 cm at 5 V with a fast response time under 2 ms. The com...

SKU: DF-SEN0556

An infrared proximity sensor that detects objects at distances of 10 ±5 mm to 80 ±20 mm by measuring reflected IR energy. It outputs a simple high/low digital signal, making it easy to integrate with Arduino and other microcontrollers. The sensor features strong ambient light rejection, fast res...

SKU: DF-SEN0523

This IR break-beam photoelectric switch detects objects by sending an invisible infrared beam from an emitter to a receiver. When a non-transparent object passes between the two and breaks the beam, the receiver outputs a signal. It works over distances up to 4 metres with a fast 0.5ms response t...

SKU: AF-5696

We are very excited to carry a new bundle supporting Adafruit friend and maker Jen Fox and her new book, Beginning Breadboarding: Physical Computing and the Basic Building Blocks of Computers!  Using fun, hands-on projects, learn what a circuit is and how it works! This book uses a common...

SKU: AF-2167

Infrared (IR) break-beam sensors are a simple way to detect motion. They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way which is sensitive to that same light. When something passes between the two, and its not transparent to ...

SKU: M5-U058

The OP.180 is an infrared reflective limit switch unit built around the ITR9606 sensor, which pairs an infrared emitting diode with a silicon phototransistor in a 180° (straight-through) orientation. When an object passes between the emitter and receiver, the IR beam is broken, triggering a digit...

SKU: SF-SEN-09299

The GP1A57HRJ00F is a slotted optical sensor (photo interrupter) with an infrared emitter on one upright and a shielded infrared detector on the other. When an object passes through the 10 mm gap between the uprights, it breaks the IR beam and the detector registers the interruption. Key Feature...

SKU: AF-5913 · MPN: ADA5913

The Adafruit STEMMA Reflective Photo Interrupt Sensor uses a TCRT1000 right-angle optical module to detect reflective surfaces. An onboard IR LED emits light, and when an object reflects it back to the IR phototransistor, the output pin drops from high toward 0V — making it easy to detect the pre...

SKU: PI-COM0613

A clear 5mm infrared LED operating at 940nm wavelength. Ideal for generic IR systems including remote controls, proximity sensors, and touchless object detection. Specifications Wavelength: 940nm (infrared) Forward Voltage: 1.5V DC Max Forward Current: 50mA Package: 5mm clear through-hole ...

SKU: AF-388

Infrared LEDs are used for remote controls (they're the little LED in the part you point at your TV) and 'night-vision' cameras, and these little blue guys are high powered ones! They are 940nm wavelength, which is what nearly all devices listen to. They're 20 degree beamwidth, and work great ...

SKU: DF-SEN0347

This infrared photoelectric switch consists of a transmitter and receiver pair that detects objects at distances up to 1.5 m with a response time under 1 ms. The infrared beam provides stable detection regardless of ambient lighting, making it suitable for both indoor and outdoor use across a −20...

SKU: EF-EF04032

The Octopus Analog Photocell Brick is a light-dependent resistor (LDR) module from the ElecFreaks Octopus Electronic Bricks series. It uses a cadmium-sulfide (CdS) photocell that changes resistance based on ambient light levels — the brighter the light, the lower the resistance. With its 3-pin co...

SKU: EC-WIS00975M

The Smart IR Module is a compact infrared transceiver board designed for IoT remote control projects. With four IR transmitters arranged for 360° coverage and an integrated IR receiver, it allows you to learn remote control codes from existing devices and then retransmit them — turning your micro...
