IR Break Beam Sensor - 3mm LEDs
·
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 Break Beam Sensor - 5mm LEDs
·
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,...
Parts Bundle for Introduction to Breadboarding by Jen Fox
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...
IR Break Beam Sensor (50cm)
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...
TSSP77038 38kHz IR Demodulator Breakout
·
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...
Motor shield for Raspberry Pi
A Raspberry Pi motor controller HAT built around the L293D dual H-bridge driver IC, designed to make building a Raspberry Pi robot easy and fun. Control up to 4 DC motors or 2 stepper motors at up to 600 mA (1 A peak) per channel. The board includes breakout connectors for IR line sensors and an...
Cherokey:4WD Basic Arduino Robot Building Kit
The Cherokey 4WD Basic Arduino Robot Kit is a perfect wheeled robot platform to build your own robot and to get started with Arduino Robot. With just a few simple steps of assembling the hardware and tuning the software, and you'll learn all about Arduino, robotics, sensors, bluetooth comm...
Smart Car Cutebot Robot for micro:bit
·
This fully-assembled and ready-to-rock robot smart car is the nicest we've seen and is incredibly easy to use with a micro:bit and MakeCode. It comes all ready to go, no soldering or screw-driver required. Simply plug in your :bit into the top slot and add three AAA batteries to get moving.The Cu...
Gravity: Arduino Digital Microwave Sensor (Motion Detection)
INTRODUCTION The microwave sensor applies the Doppler effect to detect moving objects using microwaves. This differs from the method used by a regular infrared (IR) sensor as microwave is sensitive to a variety of objects that are microwave-reflective, and its sensor...
SparkFun IR Thermometer Evaluation Board - MLX90614
An evaluation board for the MLX90614 non-contact infrared thermometer sensor. It pairs the MLX90614 with an ATmega328 running at 3.3 V (8 MHz Arduino bootloader), giving you a ready-to-use IR temperature sensor with serial output. The board comes pre-loaded with demo code that outputs temperatur...
SparkFun Triad Spectroscopy Sensor - AS7265x (Qwiic)
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...
5MP Night Vision Camera for Raspberry Pi
A 5-megapixel night vision camera module for Raspberry Pi, complete with two infrared LED boards for clear imaging in low-light and dark environments. Based on the OmniVision OV5647 sensor, it connects directly to the Raspberry Pi's CSI camera port and features an adjustable focus ring for fine-t...
Photo Interrupter - GP1A57HRJ00F
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...
37 in 1 Sensor Kit for Arduino
A comprehensive collection of 37 different sensors and modules for Arduino, covering a wide range of inputs and outputs for electronics projects. Everything comes neatly organised in a clear plastic storage case. From environmental sensing (temperature, humidity, light) to user input (joystick, ...
QTRX-HD-04A Reflectance Sensor Array: 4-Channel, 4mm Pitch, Analog Output, Low Current
·
These reflectance sensors feature a linear array of IR emitter/phototransistor pair modules in a high-density (4 mm pitch) arrangement, which makes them well suited for applications that require precise detection of changes in contrast, such as line sensing. A variety of sensor counts are av...
180° Infrared Refletive Unit (ITR9606)
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...
MAX30102 Heart Rate Sensor Module
The MAX30102 is an integrated heart rate and pulse oximetry (SpO2) sensor module. It combines red and infrared LEDs, a photodetector, and low-noise analogue electronics in a single package, communicating over I²C. Ideal for wearable health monitors, fitness trackers, and biomedical prototyping. ...
