SR602 Mini PIR Human Motion Sensor Module 1/3/5Pcs High Sensitivity Low Power for DIY Automatic Door Bell Projects

Description: SR602 Mini PIR Human Motion Sensor Module | High-Sensitivity Low-Power Infrared Presence Detector for Smart Homes, Security Systems & DIY Electronics Development Projects Features: 1. Superior Sensing Accuracy: Integrated with a pyroelectric processing chip and high-definition Fresnel lens, this module precisely captures human infrared temperature changes within its vertical sensing range, drastically cutting down false triggers for consistently reliable motion detection results. 2. Ultra-Low Power Operation: Designed with an optimized low-power circuit and high-precision SMD components, it boasts an ultra-low static current of just 20μA, minimizing energy waste. It is ideal for battery-powered devices and effectively extends the service life of your entire project. 3. Reliable Anti-Interference Performance: Fitted with a digital filtering circuit and made with high-temperature resistant FR-4 fiberglass PCB, it effectively blocks electromagnetic interference and works across a wide temperature range, maintaining stable long-term operation even in complex environments. 4. Hassle-Free Plug-and-Play Design: It comes with a standard 3-pin metal header clearly marked VCC/GND/OUT, supports wide 3.3V-15V voltage input, and is compatible with most mainstream microcontroller development boards, simplifying wiring and lowering the development barrier for DIY lovers and developers. 5. Customizable Trigger Delay: A reserved adjustable resistor slot for trigger delay lets you modify the high-level output duration after motion is detected, so you can flexibly tweak the delay time to fit different use cases and meet personalized function needs.
