The range od the delay time of the sensor become few seconds to few minutes. In our case it become 2 seconds to 200 seconds. Note : For first time of testing the PIR sensor keep delay time less . PIR Testing. We can test the PIR without interfacing with Atmega128. For this we require a set of batteries,LED,470E resistor and a few wires.

The Arduino IO expansion shield is the best match for this sound senor connecting to your Arduino. As this sensor can work at which make it compatible with Raspberry Pi, intel edison, joule and curie. PIR (Motion) Sensor Project 1: How to Make A Terrifying Halloween Gadget. This is a simple but fun application for Halloween.
This is a simple to use arduino motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the 'alarm' pin will go low. This sensor checks for infrared heat in it's detecting angle. Human body, pets and several other things emit energy that the sensor is looking for ...
일반적으로 digitalPinToInterrupt (pin) 을 써서 실제 디지털 핀을 특정 인터럽트 번호로 변환해야 한다. 예를 들어, 핀 3에 연결하면, digitalPinToInterrupt (3) 를 attachInterrupt () 에 대한 첫번째 매개변수로 쓰세요. 보드. 인터럽트에 쓸 수 있는 디지털 핀. 우노, 나노, 미니 기타 328-기반. 2, 3. 메가, 메가2560, 메가ADK. 2, 3, 18, 19, 20, 21. Micro, Leonardo, other 32u4-based.
