These sensors often come from the factory with the time potentiometer set to the center position , which corresponds to a delay of approximately three minutes . If you're testing the sensor and it stays HIGH for a long time without motion, you've discovered this default setting.
void loop() val = digitalRead(PIR_PIN);
Serial.println("Entering deep sleep for 5 seconds..."); esp_deep_sleep_start();
The most immediate advantage of this style of sensor is the size.
The module uses a simple 3-pin interface. The pinout from left to right (with the sensor facing you) is typically .
