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: 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-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: 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: SF-ROB-09453

This version of the QRE1113 breakout board features an easy-to-use analog output, which will vary depending on the amount of IR light reflected back to the sensor. This tiny board is perfect for line sensing applications and can be used in both 3.3V and 5V systems. The board’s QRE1113 IR refle...

SKU: AF-1616

The Adafruit Trellis is an open-source backlight keypad driver system designed to work with the Adafruit 4×4 elastomer keypad and 3mm LEDs. Each tile handles keypress detection and LED control for a 4×4 grid over I2C, and up to 8 tiles can be connected together for a total of 128 buttons and LEDs...

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: 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-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: DF-SEN0280

The MB1360 XL-MaxSonar-AEL0 sensor features centimeter resolution and a 10Hz read rate, and provides short to long distance detection and range information from 25cm to 1068. This sensor has the widest and most sensitive beam pattern of any unit from the XL-MaxSonar-AE sensor line and includes va...

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: 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: 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: 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: SF-SEN-15050

The SparkFun Triad Spectroscopy Sensor combines three AS7265x spectral sensors with onboard UV, visible, and IR LEDs to measure light across 18 individual frequencies — from 410 nm (UV) to 940 nm (IR). It brings light spectroscopy to the desktop, allowing you to measure and characterise how diffe...

The Adafruit Parts Pal packs LEDs, resistors, capacitors, transistors, sensors, switches, and prototyping essentials into a handy storage box — everything you need to dive into breadboard projects right away. Pair it with an Arduino, Ra...

SKU: AF-3317

The Adafruit VL53L0X is a Time-of-Flight (ToF) distance sensor from ST that uses an invisible laser to measure distances from approximately 50 mm to 1200 mm. By timing how long the laser light takes to bounce back, it delivers precise distance readings without the linearity issues or double-imagi...

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...
