Abstract


A infrared movement detector using Short Message Service based on AT89S52 microcontroller has been designed and realized. The detector can be used for monitoring any passing object in the room. This research can be used to detect up to four object in the different room. The detector was consisted one control station and one receiver station. The control station used four couple of infrared transmitter and receiver. The receiver station of mobile station was used to receive message from control station. This detector was consisted of hardware and software. The hardware was designed with infrared transmitter, an 38 kHz infrared sensor, an op-amp comparator  used to compare infrared sensor output voltage. The Transmitter emitted infrared ray and received by  sensor. Any moving object passed between them producing the output voltage of infrared receiver  change and  proceed to comparator resulting high output. This high output signal used as trigger event to running sending message procedure. And the designed software for microcontroler was written in C language. The research showed the passed object passed infrared transmitter can be detected is received and the SMS by mobile station is matched  as the location of passing object through the infrared sensor.
