Pengukuran Intensitas Cahaya Menggunakan Sensor BH-1750 Berbasis Mikrokontroler: Studi Kawasan Kampus UBP Karawang

Abstract

Sunlight is an alternative for developing renewable energy. Sunlight can be utilized as a source of energy, one of which is electrical energy. Utilization of solar energy has a positive impact in reducing air pollution and can save fossil energy. The sunlight used for the generator greatly influences how much the intensity of the sunlight used. The higher the intensity of sunlight, the higher the electrical energy absorbed by solar panels. By utilizing the Arduino microcontroller-based BH-1750 sensor, the purpose of this study was to measure the intensity of sunlight in the Buana Perjuangan University Campus area. The method used in this study was measuring the intensity of sunlight in the UBP Karawang campus area by taking a sample for 30 minutes. . Starting at 10.00 WIB - 10.30 WIB with the sun's position predicted from 80 degrees to 94 degrees. The data collected uses units of lx (LUX) with the influence of weather temperature (ᵒC). The measurement results show that the average light intensity obtained is 54627.05 lux at a sun position of 94 degrees with an ambient temperature of 34.5 degrees Celsius, resulting in an average power of 0.007998104 W/cm 2 .
