{"product_id":"pir-motion-detection-sensor-hc-sr501","title":"PIR Motion Detection Sensor - HC SR501","description":"\u003cp data-start=\"69\" data-end=\"590\" class=\"PDq2pG_selectionAnchorContainer\"\u003eThe HC-SR501 PIR Motion Detection Sensor is a passive infrared (PIR) sensor module designed to detect the motion of humans and animals by sensing changes in infrared radiation emitted by warm objects. The module incorporates a pyroelectric infrared sensor, BISS0001 motion processing IC, and a Fresnel lens, enabling reliable motion detection without emitting any infrared signals. This makes it a low-power, highly efficient solution for motion sensing applications. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"592\" data-end=\"1309\"\u003eOperating from a 4.5V to 20V DC supply, the HC-SR501 provides a 3.3V TTL digital output whenever motion is detected. The module features adjustable sensitivity (up to approximately 7 meters) and adjustable output delay (typically 5 seconds to 300 seconds) using onboard potentiometers. It also supports Repeatable (H) and Non-Repeatable (L) trigger modes, allowing users to configure the module according to their application requirements. Compatible with Arduino, ESP32, STM32, Raspberry Pi, PIC, AVR, and other microcontrollers, the HC-SR501 is widely used in security systems, automatic lighting, smart home devices, robotics, and IoT projects.\u003c\/p\u003e\n\u003ch3 data-section-id=\"etycth\" data-start=\"1316\" data-end=\"1333\" class=\"PDq2pG_selectionAnchorContainer\"\u003eKey Features\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003cul data-start=\"1335\" data-end=\"1989\"\u003e\n\u003cli data-section-id=\"g9tic9\" data-start=\"1335\" data-end=\"1376\"\u003ePassive Infrared (PIR) motion detection\u003c\/li\u003e\n\u003cli data-section-id=\"1p8jw1w\" data-start=\"1377\" data-end=\"1417\"\u003eDetects movement of humans and animals\u003c\/li\u003e\n\u003cli data-section-id=\"163aib\" data-start=\"1418\" data-end=\"1455\"\u003eBuilt-in BISS0001 PIR controller IC\u003c\/li\u003e\n\u003cli data-section-id=\"q5yp1v\" data-start=\"1456\" data-end=\"1512\"\u003eAdjustable detection distance (up to approximately 7m)\u003c\/li\u003e\n\u003cli data-section-id=\"s60mgw\" data-start=\"1513\" data-end=\"1543\"\u003eAdjustable output delay time\u003c\/li\u003e\n\u003cli data-section-id=\"1c4tybx\" data-start=\"1544\" data-end=\"1597\"\u003eRepeatable (H) and Non-Repeatable (L) trigger modes\u003c\/li\u003e\n\u003cli data-section-id=\"vz5l7z\" data-start=\"1598\" data-end=\"1642\"\u003eWide operating voltage range (4.5V–20V DC)\u003c\/li\u003e\n\u003cli data-section-id=\"jhmxae\" data-start=\"1643\" data-end=\"1666\"\u003eLow power consumption\u003c\/li\u003e\n\u003cli data-section-id=\"qze3w9\" data-start=\"1667\" data-end=\"1692\"\u003e3.3V TTL digital output\u003c\/li\u003e\n\u003cli data-section-id=\"16ficdp\" data-start=\"1693\" data-end=\"1729\"\u003eWide detection angle of up to 120°\u003c\/li\u003e\n\u003cli data-section-id=\"1oz7cwd\" data-start=\"1730\" data-end=\"1776\"\u003eFresnel lens for enhanced detection coverage\u003c\/li\u003e\n\u003cli data-section-id=\"utn9hq\" data-start=\"1777\" data-end=\"1812\"\u003eHigh immunity to false triggering\u003c\/li\u003e\n\u003cli data-section-id=\"1dcbm6k\" data-start=\"1813\" data-end=\"1846\"\u003eCompact PCB with mounting holes\u003c\/li\u003e\n\u003cli data-section-id=\"9wxqdp\" data-start=\"1847\" data-end=\"1920\"\u003eEasy interfacing with Arduino, ESP32, STM32, Raspberry Pi, AVR, and PIC\u003c\/li\u003e\n\u003cli data-section-id=\"cx2wll\" data-start=\"1921\" data-end=\"1989\"\u003eIdeal for security, automation, and occupancy sensing applications\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Roboracter","offers":[{"title":"Default Title","offer_id":46747613298742,"sku":"Y8LY53FY7A","price":79.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0715\/0731\/2694\/files\/PIR-1.png?v=1783280041","url":"https:\/\/roboracter.in\/products\/pir-motion-detection-sensor-hc-sr501","provider":"Roboracter","version":"1.0","type":"link"}
