This is a home security system that alerts the intrusion to the first floor, which is absent at night. On the first floor, an ultrasonic distance sensor and a motion sensor detect intrusion. The units between the 1st and 2nd floors are constantly communicating using the wireless device XBee WiFi, an alarm will be issued if an intrusion is detected when the lights of the first floor are off during the set time zone. At the time of the alarm, the red rotating lamp on the first floor is activated and the buzzer sounds. The second floor is equipped with an LCD display and buzzer that display information on the first floor. Since there is a detailed explanation, I hope that it will be useful as a subject for young engineers who are thinking of installing a similar system.
