    The figure (a) shows the close-range infrared detection circuit principle. The circuit realises detection of the controlled one by infrared ray close-range emitting and receiving. It can be used to realise close-range automatic instant control, such as bus's automatic door open/close control, washroom hand dryer's blowing control. The circuit consists of two parts: infrared ray emitting circuit and infrared ray receiving circuit.
