Infrared & Thermal Sensors

SKU: DF-SEN0171 | Brand: DFRobot

A passive infrared (PIR) motion sensor from DFRobot's Gravity series. It detects infrared radiation from people and animals in motion and outputs a digital HIGH signal when movement is detected — ideal for security sy...

SKU: DF-SEN0381 | Brand: DFRobot

A digital infrared proximity sensor with an adjustable detection range of 0–200 cm. It uses diffuse IR reflection to detect objects or people, outputting a digital high signal when something enters the sensing zone an...

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: DF-SEN0531 | Brand: DFRobot

The Digital IR Proximity Sensor detects objects at distances from 1 to 400 cm using a 940 nm laser emitter. It's the advanced version of the SEN0381, offering a longer sensing range and an onboard status indicator LED...

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-4667 | Brand: Adafruit

The BL412 is a compact passive infrared (PIR) motion sensor designed for detecting movement from people and animals at distances of approximately 3–8 m. Much smaller than standard PIR modules, it is well suited for un...

SKU: M5-U050 | Brand: Little Bird

Including 8 Different Units: Earth, Angle, PIR, HUB, Light, RGB, IR, ENV  

SKU: M5-U058 | Brand: Little Bird

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 pa...
