Portable illumination meter

Overview

I often have to pay attention to whether the lighting environment for children at home is sufficient for reading, so I made a portable lighting meter. The sensor uses BH1750F, the microcontroller is an STC microcontroller, the display uses an OLED, and the power supply uses two AAA dry batteries.

See the attachment for the microcontroller program.
