บทนำ
A illuminance sensor is a precision device designed to measure Illuminance in and around tunnels, enabling automatic lighting control for safer driving and energy efficiency. It works by using a Photodiode to convert light into electrical signals, which are processed to match human eye sensitivity. Widely applied in highway and railway tunnels, urban underpasses, and intelligent traffic systems, it provides stable, real-time data for smart lighting and safety management.
