5 Pack PIR Motion Sensor Module HC SR501 Infrared for Arduino Projects with Adjustable Timing 0.5 to 200 Seconds Dope for Home Security Auto Lighting DIY Automation Toys and Maker Prototyping

5-pack PIR sensor modules with adjustable timing ✔️ Adjustable 0.5s-200s timing via potentiometer; 5 pcs

These HC-SR501 PIR infrared sensor modules are a handy set for motion-based projects. They’re commonly used in home security, auto lighting, toys, industrial automation, and maker prototyping. Each unit houses only the infrared sensor element (no emitter) and detects human-body infrared radiation. A solder jumper controls retrigger timing; you’ll need to solder it to enable retrigger mode.
