Infrared & Thermal Sensors

SKU: AF-3985 | Brand: Adafruit

This T-Slot Photo Interrupter with Cable 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...

SKU: DF-SEN0523 | Brand: DFRobot

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 outpu...

SKU: LB-PIR-CABLE | Brand: Little Bird

A compact passive infrared (PIR) motion sensor housed in a protective case with a 45cm cable. Detects motion within a 6-metre range and 120° field of view, making it ideal for security systems, automatic lighting, and...

SKU: SF-SEN-09299 | Brand: SparkFun

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,...

SKU: SF-SEN-13285 | Brand: SparkFun

This is a simple to use 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 unit works great from 5...

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: SF-BOB-09322 | Brand: SparkFun

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 (>...

SKU: TB-XC4444 | Brand: Little Bird

A pyroelectric infrared (PIR) motion sensor module for Arduino and microcontroller projects. It detects movement from people and animals by sensing changes in infrared radiation, outputting a digital high signal when ...

SKU: EF-EF10030 | Brand: ElecFreaks

A passive infrared (PIR) motion sensor module based on the BISS0001 IC, capable of detecting human movement at up to 7 metres. Outputs a digital high signal when motion is detected, making it easy to interface with Ar...

SKU: PI-COM1702 | Brand: Pimoroni

This sensor is composed of an infrared emitter on one upright and a shielded infrared detector on the other. By emitting a beam of infrared light from one upright to the other, the sensor can detect when an object pas...
