Story

Dalam pemakaian lampu di setiap rumah jika sesekali lupa mematikan lampu, memang tidak berpengaruh besar dalam biaya listrik karena watt lampu yang kecil, namun akan menjadi masalah biaya jika sering tidak di matikan, mak kami membuat sensor cahaya yang secara otomatis dapat mematikan lampu dan menyalakan lampu, dengan menghubungkan sensor yang terdapat pada lampu dengan internet & smartphone. Sehingga, ibu rumah tangga dapat meminimalisir pengeluaran biaya listrik, dan juga dapat menjaga ketahanan lampu, terutama saat menjelang hari raya idul fitri.
