The circuit can be protect against theft. When the family leaves bedroom, switch K1 is closed, the circuit begins to work . As long as  someone enters the room for a period of time, it will sound the alarm. Passive Infrared Radiation (PIR) sensor detects the change in infrared radiation of warm blooded moving object in its detection range.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003e Sensitivity range: up to 20 feet (6 meters) 110° x 70° detection range.\u003c\/li\u003e\n\u003cli class=\"TrT0Xe\"\u003eComplete with PIR, Motion Detection.\u003c\/li\u003e\n\u003cli class=\"TrT0Xe\"\u003eDual Element Sensor with Low Noise and High Sensitivity.\u003c\/li\u003e\n\u003cli class=\"TrT0Xe\"\u003eStandard TTL Output.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003chr\u003e\n\u003ch4\u003e\u003cstrong\u003ePackage Includes:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003e\u003cspan\u003e1 x Pro-Range HC-SR501 PIR Based Human body sensing Anti-theft Alarm DIY Electronic kit for students \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSpecification :\u003c\/span\u003e\u003c\/p\u003e\n\u003ctable class=\"specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eItem Type:\u003c\/td\u003e\n\u003ctd\u003eKit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel:\u003c\/td\u003e\n\u003ctd\u003eSensor Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Range\u003c\/td\u003e\n\u003ctd\u003eup to 20 feet (6 meters) 110° x 70° detection range.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature (°C):\u003c\/td\u003e\n\u003ctd\u003e15 ~ +70 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage (V):\u003c\/td\u003e\n\u003ctd\u003eMar-20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e0.029 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Dimensions\u003c\/td\u003e\n\u003ctd\u003e9 × 7 × 1 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Jaideep Robotics","offers":[{"title":"Default Title","offer_id":46456365842605,"sku":"1187626","price":471.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0773\/7638\/9293\/files\/download-2026-06-29T190857.586.avif?v=1782740346","url":"https:\/\/jaideeprobotics.com\/products\/pro-range-human-body-sensing-ir-pyroelectric-infrared-sensor-anti-theft-alarm-electronic-kit-students-electronic-principle-study-hc-sr501","provider":"Jaideep Robotics ","version":"1.0","type":"link"}
