The PIR Sensor works by measuring the \u003cstrong\u003einfrared (IR) light\u003c\/strong\u003e emitted from, or reflected by, that object.\u003c\/p\u003e\r\n\u003cp\u003eThe \u003cstrong\u003eHi-Link LD2410 mmWave radar sensor\u003c\/strong\u003e is a game-changer for precise \u003cstrong\u003ehuman presence detection\u003c\/strong\u003e. Unlike traditional PIR sensors that only trigger on movement, the LD2410 detects both \u003cstrong\u003estationary occupants\u003c\/strong\u003e (e.g., someone sitting or sleeping) and \u003cstrong\u003emotion\u003c\/strong\u003e. This makes it ideal for automation scenarios where accuracy is critical.\u003c\/p\u003e\r\n\u003cp\u003eIn this tutorial, we’ll understand the \u003cstrong\u003eLD2410\u003c\/strong\u003e capabilities by interfacing it with an \u003cstrong\u003eESP32 microcontroller\u003c\/strong\u003e. We will create a versatile \u003cstrong\u003eHuman Presence Detection System\u003c\/strong\u003e. The setup includes two LEDs: a \u003cstrong\u003ered LED\u003c\/strong\u003e to signal when a person is stationary (at rest) and a \u003cstrong\u003egreen LED\u003c\/strong\u003e to indicate active motion. Additionally, \u003cstrong\u003ereal-time detection data\u003c\/strong\u003e, including distance metrics (\u003cem\u003eup to 6 meters\u003c\/em\u003e), will be displayed on a 0.96-inch \u003cstrong\u003eOLED screen\u003c\/strong\u003e, providing immediate visual feedback.
