Sistem Notifikasi Pemesanan Makanan Berbasis Mikrokontroler Dengan Radio Frequency

Abstract

Food ordering system in Indonesia is still inefficient because there is no tool that can reduce the notification queue and replace the function of servars. This study aims to develop a cheap and simple notification system for food ordering based on microcontroller with radio frequency. The system consists of 2 main devices: a transmitter for the seller and a receiver for the customer. These devices are connected to each other by a radio signal with a frequency of 433 MHz using Amplitude Shift Keying (ASK) modulation. It is found that this device can make the queuing system becomes more efficient by giving notification in the form of LED light and buzzer sound. The maximum distance between the transmitter and receiver is 70-80 m.
