SKU: DF-SEN0239 | Brand: DFRobot

A digital infrared proximity sensor with adjustable detection range from 0 to 200 cm. Outputs a simple digital signal — HIGH when an obstacle is detected, LOW when clear. The detection threshold is adjustable via a re...

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: DF-SEN0522 | Brand: DFRobot

This human body sensing switch adopts an infrared detection way to control load switch. It offers a detection range of 5~8m, high sensitivity, and reliability. The sensor has an adjustable delay function and the ...

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 &...

##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. ...

SKU: AF-5022 | Brand: Adafruit

The Adafruit Proximity Trinkey is a tiny USB-A development board built around the APDS9960 multi-function sensor and an ATSAMD21 microcontroller. Plug it into any USB port and you instantly have proximity, colour, amb...

SKU: AF-4161 | Brand: Adafruit

The Adafruit VCNL4040 is a two-in-one proximity and ambient light sensor from Vishay. It measures proximity from 0 to 200 mm (~7.5 inches) using an on-board IR LED, and ambient light from 0.0125 to 6,553 lux — all ove...

SKU: DF-SEN0263 | Brand: DFRobot

We can divide temperature measurement in to two types: contact and non-contact. Contact measurement can only accurately measure temperature when the testing object and the sensor reach thermal equilibrium. This ca...

SKU: DF-SEN0018 | Brand: DFRobot

This is a simple to use arduino motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the 'alarm' pin will go low. This sensor c...

SKU: SF-ROB-09454 | Brand: SparkFun

The SparkFun QRE1113 Line Sensor Breakout (Digital) is a compact IR reflectance sensor board that outputs a digital signal based on surface reflectivity. It uses a capacitor discharge circuit — the faster the 10 nF ca...

SKU: AF-6426 | Brand: Adafruit

The Adafruit STHS34PF80 is a compact IR presence and motion sensor that detects human and animal presence up to 4 metres away — without requiring a lens. Unlike traditional chunky PIR sensors with simple digital outpu...

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-4871 | Brand: Adafruit

A compact passive infrared (PIR) motion sensor that detects movement from people and animals at distances of 2 to 5 metres. Much smaller than standard PIR modules, this sensor is ideal for unobtrusive projects and plu...
