Rancang bangun sistem keamanan pagupon menggunakan sensor ultrasonic hc-sr04 dan alarm berbasis arduino dengan aplikasi di android
Daftar Isi:
- Factor of safety and comfort that is becoming a major problem for the occupants of the lover pigeo. At the moment there is increasingly widespread theft of pigeons, theft is carried out in the form of planning and when there is a chance. Especially pagupon which has no security so that it is easily accessible to foreigners. For this reason, a pagupon safety device is needed that can remind that there are foreigners who enter without permission. This tool utilizes Ultrasonic HC-SR04, Bluetooth HC-05, Arduino, Buzzer and Sirine sensor technology as the main purpose for the output. Application of bluetooth in android smartphone connect bluetooth module with HC 05 and ic 555 using the Arduino Uno, which served as a tool of control. With the implementation of the applied to the pagupon can be controlled with an effective maximum distance if without any hindrance as far as 13 meters and the effective maximum distance if the existence of the barrier as far as 9 meters Ultrasonic sensor will detect the motion detected work optimally at a distance of 0,5 Meter and with a maximum distance of 4 Meter by the sensor. The initial warning buzzer when the sensor has detected movement with, then a siren sound continues. Keywords: Arduino Uno, Bluetooth HC-05, Sensor Ultrasonic HC-SR04, Buzzer, and ic ne555 (Sirine).
