It operates on a \"set-and-forget\" principle, with its sensitivity and delay time pre-calibrated for general-purpose use.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003e \u003cbr\u003e\u003c\/span\u003e\u003cstrong\u003eWhy it’s a Portable \u0026amp; IoT Essential:\u003c\/strong\u003e\u003cspan\u003e \u003cbr\u003e• Space-Saving Design: At roughly the size of a finger-tip, it can be hidden inside 3D-printed cases, small lamps, or picture frames without being intrusive. \u003cbr\u003e• Ultra-Low Power: It is specifically engineered for low-power standby. This makes it perfect for battery-powered IoT nodes that need to last for months on a single charge. \u003cbr\u003e• Wide Voltage Range: Like the larger version, it accepts anywhere from 4.5V to 20V, but outputs a clean 3.3V digital HIGH signal. This makes it natively compatible with both 5V Arduinos and 3.3V chips like the ESP32. \u003cbr\u003e• Simplicity: With no potentiometers to adjust, it provides a consistent, factory-calibrated experience that is less prone to \"drift\" caused by vibration.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cstrong\u003e \u003cbr\u003eTechnical Capabilities:\u003c\/strong\u003e\u003cspan\u003e \u003cbr\u003e• Detection Range: Approximately 3 to 5 meters, providing a smaller but more focused detection \"bubble.\" \u003cbr\u003e• Fixed Delay: Once motion stops, the output stays HIGH for approximately 8 seconds before resetting. \u003cbr\u003e• Digital Logic: Outputs a simple HIGH (3.3V) when motion is detected and LOW (0V) when the area is clear.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003e \u003cbr\u003e\u003c\/span\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e\u003cspan\u003e \u003cbr\u003eThe HC-SR505 is the primary choice for closet\/cabinet lighting, portable security gadgets, battery-operated welcome mats, and miniature robotics. \u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"TinkEdge","offers":[{"title":"Default Title","offer_id":46404571168967,"sku":"TE-IRSE-084","price":105.93,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6620\/6407\/files\/MiniInfraredPIRMotionSensorInfraredDetectorModule_1.png?v=1776774013","url":"https:\/\/shop.tinkedge.tech\/products\/hc-sr505-mini-infrared-pir-motion-sensor-infrared-detector-module","provider":"TinkEdge","version":"1.0","type":"link"}
