Hw416b Pir Sensor Datasheet Better Jun 2026
#include <esp_sleep.h>
If you find your PIR sensor is triggering randomly, the "better" way to handle it isn't just software—it's hardware. hw416b pir sensor datasheet better
The most immediate advantage of this style of sensor is the size. #include <esp_sleep
#define PIR_PIN GPIO_NUM_4
volatile bool motionDetected = false; unsigned long lastMotionTime = 0; const unsigned long MOTION_HOLD_MS = 3000; // Match sensor's delay unsigned long lastMotionTime = 0
