적외선 움직임감지센서를 이용한 차량 충격감지 및 실내침입감지 센서 시스템 개발

In general, car intruder sensor detects object using ultrasonic signal. However, ultrasonic sensor has some disadvantages such as high cost and sensitive to external ultrasonic signal. This problem will be solved by modulated infrared signal. Shock sensor also uses ultrasonic signal, but it cannot be integrated with intruder sensor. Therefore, new sensor system will be proposed that can overcome the existing problems. And car intruder sensor will be integrated with shock sensor in one system.
