Oiyagai 2pcs SR602 PIR Motion Sensor Module Pyroelectric Infrared Human Detection Switch Board for DIY Electronics

• PIR Motion Detection Module — Uses a pyroelectric infrared sensor to detect human body motion based on changes in infrared radiation.
• SR602 Compact Design — Small-form PIR sensor board with integrated signal processing, suitable for space-constrained electronic projects.
• Pre-Soldered Pin Header — Pin header is factory soldered, allowing direct connection to control boards or breadboards without additional assembly.
• Adjustable Output Time — Output high-level duration is adjustable (approx. 2.5 seconds to 1 hour); blocking time is fixed and not adjustable.
• Passive Sensor Notes — Requires external power supply; output is a signal level only, not a relay or load switch, and cannot directly drive high-power devices.
