Abstract :
Crime in the current era is not impossible, especially during the Covid-19
pandemic which makes employment increase. Unemployment is increasing,
causing crime to also increase. Security for a room is very important to avoid the
rise in crime rates. In this study, the authors designed a security system that is
expected for users to create security in a room.
This security system uses a Raspberry Pi 4 to be used as the main device
in the process of sending data and using the WhatsApp application as a data
recipient in the form of a notification message "ADA PENYUSUP". In detecting
an object at human temperature using a PIR sensor. This system requires an
internet connection which is used to assist the performance of the Raspberry Pi 4
in sending data to WhatsApp.
The results obtained from this test are that the sending of notification
delay messages has an average reading time of 1.499 seconds. The output voltage
generated by the PIR sensor when it detects an object in front of the sensor is 3.37
volts. The PIR sensor can detect an object's movement with a maximum distance
of 7 meters and with a sensitivity angle the PIR sensor can work when the object's
position is at an angle of 40? to 140
?.
