Abstract

Perkembangan teknologi mikrokontroler menimbulkan ide-ide dan inovasi manusia untuk memanfaatkan secara optimal termasuk dalam bidang pengukuran ilmu fisika. Perancangan perangkat keras dan perangkat lunak alat praktikum dilakukan untuk mengukur intensitas cahaya (lux) menggunakan sensor cahaya BH1750 dengan sensor ultrasonik HY�SRF05 untuk mengukur jarak ukur intensitas cahaya berbasis mikrokontroler NodeMCU ESP8266 dan data dikirimkan ke spreadsheet sehingga data dapat disimpan secara real time. Hasil uji karakteristik sensor cahaya BH1750 memiliki kemampuan yang baik dengan rata-rata nilai akurasi 99,49%, presisi 99,43%, dan error 0,13% kalibrasi dilakukan menggunakan light meter Krisbow KW06-266. Sensor ultrasonik HYSRF05 untuk mengukur jarak sudah memiliki akurasi yang baik saat dikalibrasi dengan penggaris. Alat ukur ini mampu mengirim data pengukuran sejauh 80m secara wireless. Intensitas cahaya (lux) lampu yang diuji yaitu Lampu Pijar, Lampu CFL (Compact Fluorescent Lamp), dan Lampu LED (Light Emitting Diode) dengan warna lampu warm white untuk mengetahui pengaruh jarak terhadap intensitas cahaya (hukum kuadrat terbalik), pengaruh daya terhadap intensitas cahaya, dan pengaruh tegangan terhadap intensitas cahaya.
