SKU: SF-BOB-08688

Basic breakout board for the TEMT6000 Ambient Light Sensor. Only what you need, nothing you don’t. Sensor acts like a transistor - the greater the incoming light, the higher the analog voltage on the signal pin. Documents: Hookup Guide Datasheet Bildr Tutorial GitHub

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...

##Introduction The Gravity: Photo Interrupter Module integrates a high-performance ITR9608 photoelectric switch. Its compact design and easy operation make it an ideal choice for electronic projects and applications. Whether for robotics, automation equipment, or counting systems, this module pro...

SKU: SF-SEN-09088

This is a very small light sensor. A photocell changes (also called a photodetector, photo resistor, CdS or photoconductive cell) resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something).Fe...

SKU: AF-161 · MPN: 161

CdS cells are little light sensors. As the squiggly face is exposed to more light, the resistance goes down. When its light, the resistance is about 5-10KΩ, when dark it goes up to 200KΩ. To use, connect one side of the photo cell (either one, its symmetric) to power (for example 5V) and the o...

SKU: AF-3986 · MPN: 3986

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 across the gap, to the detector on the other side. This makes it perfect for detecti...

SKU: AF-2680 · MPN: 2680

SKU: SF-BOB-09322

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 an...

SKU: AF-3930 · MPN: 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: AF-2167 · MPN: 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 ...
