IR Break Beam Sensor (50cm)
SKU: DF-SEN0503 | Brand: DFRobot
An infrared break-beam sensor pair for simple, reliable motion detection. The emitter sends a beam of invisible IR light to the receiver — when an object passes between them and breaks the beam, the receiver outputs a...

IR Break Beam Sensor - 5mm LEDs
SKU: AF-2168 | Brand: Adafruit
Infrared (IR) break-beam sensors are a simple way to detect motion. They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way which is sensitive to that s...

Mini Basic PIR Sensor - BS412
SKU: AF-4666 | Brand: Adafruit
A compact passive infrared (PIR) motion sensor that detects movement from approximately 3–8 metres away. Much smaller than standard PIR modules, making it ideal for unobtrusive, space-constrained projects. Fully self-...
