I would like to share a project to create a simple optical proximity sensor that can be used as an optical limit switch or used as, for example, a proximity light switch. A special feature in this project is the principle of protection against parasitic infrared study and simple logic of work. It can be used as a basis for development. In the ready-made firmware for the project, there are options, an optical limit switch, an optical light switch, and an optical switch with auto-off time.
