Abstract

Telah dilakukan rancang bangun detektor sederhana yang mengubah energi gelombang radio (radio frequency) dari sinyal smartphone menjadi energi listrik. Rancangan detektor sinyal radio frequency terdiri dari rangkaian LC, IC LM386 dan Arduino Uno. Smartphone yang dihidupkan akan memancarkan gelombang radio yang akan melewati antena. Gelombang radio akan menginduksi tegangan ke antena dan akan mengubahnya menjadi energi lisrik. Pengolahan data dilakukan dengan menggunakan mikrokontroler Arduino Uno yang mengontrol LED dan buzzer sebagai indikator peringatan terdeteksinya sinyal radio frequency. Detektor dapat menangkap sinyal radio frequency dari smartphone pada jarak maksimal 3,5 cm tanpa harus dilakukan panggilan atau pengiriman teks dan dapat mendeteksi sinyal frekuensi elektromagnetik (30 MHz – 300 MHz) pada jarak maksimal 35 cm.

 

A simple detector design has been done which converts radio wave energy from radio signals to electrical energy. The design of the radio frequency signal detector consists of a series of LC, IC LM386 and arduino uno. The smartphone that is turned on will emit radio waves that will pass through the antenna. Radio waves will induce a voltage to the antenna and will convert it into electrical energy. Data processing is performed using the arduino uno microcontroller which controls LED and buzzer as a warning indicator when radio frequency detected. The detector can capture radio frequency signals from a smartphone at a maximum distance of 3.5 cm without having to make calls or send texts and can capture electromagnetic frequency (30 MHz – 300 MHz) signals at maximum distance of 35 cm.
