Hw416b Pir Sensor Datasheet Better Online

At first glance, it looks identical to the famous HC-SR501. In fact, the HW416B is often considered a direct, sometimes improved, clone of that design. But here is the problem every maker faces: pinMode(PIR_PIN, INPUT_PULLDOWN); #include &lt;esp_sleep

lastMotionState = motionState; delay(50); // Simple debounce At first glance

void setup() Serial.begin(115200); bootCount++; Serial.println("Wake #" + String(bootCount));

Serial.println("Entering deep sleep for 5 seconds..."); esp_deep_sleep_start();
