Abstract & Overview
This research discusses the design of a lux meter based on the TSL2561 sensor. The testing was conducted by comparing the measurement result of lux using the designed lux meter device with a reference device. The testing data was obtained from three different smartphones over a period of three minutes, but only 10 data points were presented. The test results revealed differences between the readings of the TSL2561 sensor and the reference device for each smartphone. These difference were attributed to the non-propotional positioning of the flashlight when directed into the device’s box, resulting in suboptional light reception by the sensor. The conclusion of this study is that the lux meter device can function effectively when the flashlight’s positioning and stability are properly maintained. The accuracy level was found to be 71% between the sensor data and reference data for smartphone A, and 99% for smartphone B
