| Abstract: | A light intensity measuring instrument is designed based on light intensity sensor BH1750FVI. Low cost microcontroller isused for control,and I2C interface is used to data transmission. Measured values of light intensity are displayed on general NOKIAS110 LCD in real time. The system can effectively achieve accurate monitoring of 0- 65 535 lx intensity. It is a high-performance light intensity monitoring device. |
