It captures changes in infrared radiation emitted by moving objects within its active range, making it a reliable \u003cstrong\u003epir motion sensor\u003c\/strong\u003e for automation tasks. Because the \u003cstrong\u003ehc sr501\u003c\/strong\u003e includes adjustable sensitivity and timing controls, users can fine-tune detection performance across a wide range of applications.\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003eOperating at 5V DC, this \u003cstrong\u003epir sensor\u003c\/strong\u003e is commonly used in security alarms, automatic lighting, and home automation projects. With a detection distance of up to 7 meters depending on conditions, the \u003cstrong\u003ehc sr501\u003c\/strong\u003e integrates seamlessly with popular platforms such as \u003cstrong\u003eArduino and Raspberry Pi.\u003c\/strong\u003e Its low power consumption also makes it suitable for portable or battery-powered devices, where a \u003cstrong\u003epir motion sensor\u003c\/strong\u003e must remain energy-efficient.\n\u003cdiv\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Details – hc sr501 reference\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003eItem Type: Sensor\u003c\/li\u003e\n\u003cli\u003eModel Type: Motion Sensor Module\u003c\/li\u003e\n\u003cli\u003eModel No.: HC SR501\u003c\/li\u003e\n\u003cli\u003eOperating Voltage (V): 4.5 to 20\u003c\/li\u003e\n\u003cli\u003eAvg.
