SISTEM PEMANTAU RUANG JARAK JAUH DENGAN SENSOR PASSIVE INFRARED BERBASIS MIKROKONTROLER AT89S52
Abstract: This research
describes about the design of the room detection system using a Passive
Infrared sensors (PIR) controlled by Microcontroller AT89S52 for remote control
application. The output of the PIR is a low logic when it captures the heat
waves of the human body. The output PIR is connected to the port 1.7 on
Microcontroller in high logic. The maximum distance is 5 meters for the sensor
to detect an object. When there is a signal sent by PIR, the Microcontroller
processes the data and activates the buzzer to beep and the stepper motor to
stop. Microcontroller also sends data through the RS-232 that continues a
signal to the personal mobile phone. In
order that the message is able to be sent, then first, messages must be
programmed and stored in the Microcontroller AT89S52. The average message
delivery time is 8.8 seconds. The recipient can turn the alarm of system on or
off by a missed call.
