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-SEN0556 | Brand: DFRobot

An infrared proximity sensor that detects objects at distances of 10 ±5 mm to 80 ±20 mm by measuring reflected IR energy. It outputs a simple high/low digital signal, making it easy to integrate with Arduino and other...

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: SF-PRT-18582 | Brand: SparkFun

This IR proximity contactless button makes for a good replacement for typical push buttons in situations where touching the button isn't required or desirable (especially in this day and age). This button includes a b...

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: 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...

SKU: AF-466 | Brand: Adafruit

The VCNL4010 sensor is a nice way to add a small-distance proximity sensor to your microcontroller project. For longer distances (in the range of cm, you can use a SHARP IR distance sensor, but those are only good ...

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...
