Abstract

• The intensity of solar radiation and UV radiation are measured using BH1750 by BH1750 sensor and light sensor and ML 8511 UV sensor respectively. The process is implemented by using microcontroller. As BH 1750 light sensor is inter- integrated circuit (I2C) device, it is connected to microcontroller with I2C mode. The data from each sensor are sent to Arduino microcontroller and then, data are displayed on LCD. Simultaneously, the intensity of light and UV radiation are logged in excel spreadsheet directly using the parallex data acquisition (PLX-DAQ) software. These data are uploaded directly to Microsoft(MS) excel spreadsheet directly with the accompanying the current date and time.
