Jammer

JWS Jammer dengan Database Jadwal Waktu Shalat Bulanan

Asep Kurniawan

Jammer merupakan alat pengacak/blokir sinyal handphone/hp dapat digunakan di tempat ibadah untuk me-nonaktifkan perangkat cellular sehingga tidak bisa dipanggil/memanggil dengan tujuan menjaga tempat ibadah dari kebisingan dering ponsel.

Penggunaan jammer/jamming/repeater sinyal hp bisa mengganggu hak orang lain dan berpotensi melanggar undang-undang telekomunikasi, gunakan dengan bijak

Jadwal Shalat

Jadwal shalat berubah-ubah setiap hari tergantung posisi matahari dan bulan, hal ini membuat perangkat digital harus mampu mengikuti perubahan ini. Beberapa metode penggunaan jadwal shalat shalat digital :

  1. Jadwal manual, yaitu jadwal rata-rata dari setiap waktu-waktu shalat
  2. Jadwal database, yaitu jadwal yang tersimpan dalam tabel, bisa mingguan, bulanan atau tahunan
  3. Jadwal Matahari, yaitu penghitungan waktu shalat menggunakan posisi peredaran matahari, dengan memasukkan variabel posisi lintang, bujur, dan tanggal.
  4. Jadwal online, dengan mengambil data dari server online setiap hari.

Skema JWS Jammer menggunakan arduino:

Komponen yang digunakan dalam JWS Database Jadwal Waktu Bulanan:

  1. Arduino Uno
  2. LCD 1602 I2C Backpack
  3. RTC DS3231
  4. Relay untuk jammer
  5. 3x LED
  6. 3x TOmbol
