Design and Development Lux Meter

Abstract

This paper presents development of digital photometerinstrument by using Microcontroller based on UNO Funduino processing and Module GY-302 (Ambient Light Sensor Module) to detect light intensity. The instrument measures light intensity from Sun and fluorescent light bulb with instrument model Heavy Duty Light Meter. The results show that light intensity of fluorescent light bulb has maximum error 1.97% and light intensity of the has maximum error 4.53%. The error is within acceptable interval. Therefore, the implementation can be efficiently used to measure the light intensity from sun and fluorescent light bulb and help to decrease the instrument importation from abroad because there are not enough devices to users. Moreover, it is inexpensive and easy to use.
