Abstract

Telah dibuat alat pendeteksi intensitas cahaya berbasis Sensor Light Dependent Resistance (LDR) dengan modul arduino Nano V3. Alat ini dibuat dengan memanfaatkan perubahan resistansi pada sensor LDR ketika dikenakan cahaya. Sensor Light Dependent Resistance (LDR) ini belum dikalibrasi sesuai standar pabrik, sehingga digunakan alat ukur intensitas cahaya luxmeter L200 yang sudah terstandarisasi untuk proses kalibrasi alat. Alat kemudian di program dengan software Open-Source arduino agar hasil pembacaaan alat dapat ditampilkan pada layar LCD 16x2. Hasil yang didapat yaitu pada saat belum terkalibrasi, alat luxmeter berbasis sensor LDR ini pembacaannya berbeda jauh dengan Luxmeter yang terstandar berkisar antara 1:1,5 dan setelah dikalibrasi error yang dihasilkan pada sensor ini mengecil dan pembacaan sensor LDR mendekati dengan alat ukur luxmeter L200 yang sudah terstandarisasi.Light intensity detection devices have been developed based on Light Dependent Resistance (LDR) sensor with arduino Nano V3 module. This tool is made by exploiting the resistance change in the LDR sensor when it is applied with light. This Light Dependent Resistance (LDR) sensor has not been calibrated to factory standards, so a standard L200 luxmeter L200 intensity gauge has been employed for calibration process. The tool is then in the program with the arduino Open-Source software so that the reading results of the tool can be displayed on the 16x2 LCD screen. The results obtained when not yet calibrated, are differ greatly with the standardized Luxmeter which ranged from 1: 1.5 and after been calibrated the error result in this sensor is become smaller and the constructed LDR sensor readings are close to standardized luxmeter L200.
