Breadboard-friendly Mini PIR Motion Sensor with 3 Pin Header

OverviewPinoutWiringRelated groups
Breadboard-friendly Mini PIR Motion Sensor with 3 Pin Header — Adafruit — 4871

PIR sensors are used to detect motion from pets/humanoids from about 5 meters away (possibly works on zombies, not guaranteed). This sensor is much smaller than most PIR modules, which makes it great for unobtrusive projects.

Light and colour

Photoresistors and color sensors both respond to light, but they expose very different signals and are not sensible drop-in substitutes.
