Abstract

Robot cerdas pemadam api beroda yang berguna untuk menemukan dan memadamkan api serta dapat bergerak secara otomatis dengan pemantauan berbasis wifi telah dirancang bangun. Robot terdiri dari sensor api KY-026 dan sensor ultrasonik HC-SR04 dilengkapi dengan kamera wifi dan pompa air yang diprogram dalam mikrokontroler Arduino UNO R3. Dari hasil pengujian didapatkan robot dapat menelusuri sirkuit, memantau keadaan sekitar, mendeteksi api dan memadamkannya dengan baik. Robot berhasil mendeteksi api dan memadamkannya berdasarkan tegangan keluaran dari sensor api KY-026. Jika tegangan sensor api berada di bawah 4,1 V maka robot akan berhenti dan mengaktifkan pompa air yang dilengkapi dengan motor servo untuk memadamkan api lilin. Namun s[ensor ultrasonik tidak bisa mengukur jarak jika posisi sensor ultrasonik terhadap dinding/objek dalam kondisi serong. Hal ini terjadi karena sudut pantul gelombang ultrasonik lebih besar dari 150 sehingga receiver sensor tidak dapat menangkap gelombang yang dipantulkan objek dengan baik. Kondisi ini mengakibatkan pengukuran jarak menjadi error dan berpengaruh pada gerak robot.

Kata Kunci : Robot pemadam api, sensor api, sensor ultrasonik, Arduino UNO R3
