follow to similar logic https://github.com/danieleds/Asus-Zenbook-Ambient-Light-Sensor-Controller

@yinyue200 hello,

That's interesting idea, but honestly, I have don't know how to read backlight sensor data as my device(s) don't even have it.
I see that the linux tool you linked seem to read it from /sys/bus/acpi/devices/ACPI0008:00/ali

I'm not sure what would be an equivalent in windows. Since you have a sensor, may be you can experiment and check if it returns something by doing it a way app currently accesses ATKACPI driver ?
