The photoelectric switch circuit is as shown. When there is no light, the system is in a certain working state, such as on-state or off-state. When the photovoltaic cell is illuminated by light
, it generates a high electromotive force. As long as the light intensity is greater than a certain set threshold, the system changes its working state to achieve the purpose of switching. This kind of
switching circuit is mostly used in various control systems.
