hello,
i am doing a project of a sleepy driver warning system, i used ir led and photodiode as the sensor for the eyeblink detection. the project was done, but a problem exist, somebody said that our project is very dangerous from the eye because of the infrared rays transmited to the eye.. is that really true?
why is it that theres a lot of related project was done since it is not safety? how will i defend such issue>? really need ur opinions to defend our project. below is our full schematic diagram of our project.
