The Feather nRF52840 Sense takes the popular Feather nRF52840 Express and adds a suite of on-board environmental and motion sensors. It features Bluetooth Low Energy, native USB, CircuitPython and Arduino support, plu...

SKU: AF-5913 | Brand: Adafruit

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 phototransis...

SKU: LB-LS0633 | Brand: Little Bird

A pack of 50 through-hole photoresistors (light-dependent resistors / LDRs) with a 5 mm diameter sensing element. These components change their resistance based on the amount of light hitting the sensor — resistance d...

SKU: AF-2349 | Brand: Adafruit

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 &...

SKU: AF-5970 | Brand: Adafruit

The Adafruit TSMP96000 "Code Learning" Infrared IR Receiver Breakout detects IR signals across a wide frequency range of 20–60 KHz, making it perfect for "code learning" applications where you need your device to work...

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: DF-SEN0164 | Brand: DFRobot

This adjustable infrared sensor features a high-sensitivity photoreflector to perform distance detection function,ranging from 3cm to 50cm. When the infrared light emitted by the emitter gets reflected on a surface...

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 ...
