The PIR Mini Sensor detects motion up to 12 feet (3.65 meters) away. Like the other passive infrared sensors we carry, the PIR Mini contains a pyroelectric device that senses and responds to changes in the infrared levels emitted by nearby objects.

Smart Motion Sensor, WiFi PIR Motion Sensor for Alarm System, Mini Infrared Motion Sensor with App Remote Monitoring, Triggering Lights and Scenes, Compatible with Alexa.1 PCS

This sensor is much smaller than most PIR modules, which makes it great for unobtrusive projects. It's also fully-contained - only needs power, ground and a resistor to set the delay time - and breadboard or perfboard friendly.

2PCS Mini Pir Motion Sensor Switch, DC 5-24V Auto PIR Infrared Motion Sensor Detector LED Light Strip Switch 5.5 DC Plug for DIY LED Lighting, Light Sensor, Time & Distance Adjustable (Black & White)

This sensor is much smaller than most PIR modules, which makes it great for unobtrusive projects. It's also fully-contained - only needs power and ground, and it's breadboard or perfboard friendly. Usage is super simple: You can power it from 3 to 12V DC, there's an onboard regulator.

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. It's also fully contained and very configurable.
