lastMotionState = motionState; delay(50); // Simple debounce

👉 “HC-SR501 datasheet” (not HW-416B) hw416b pir sensor datasheet better

// Turn off LED after hold time (simulates retrigger management) if (millis() - lastMotionTime > MOTION_HOLD_MS) digitalWrite(LED_PIN, LOW); lastMotionState = motionState

Here is the for the HW416B, based on lab testing and community validation. Here is the for the HW416B
