Abstract
With the development of society and economy, people's living standard continues to improve, the corresponding cross infection diseases are constantly taking place, people used to wash your hands are dry hands are hand use towel dry water, thus causing cross infection of the consequences. This leads us to the daily life of the people of hand washing to dry hands, attention to detail. So people designed hand dryer. This design is mainly a reflection type infrared sensor, the infrared ray to realize the automatic control of hand switch, infrared automatic control device of hand by the infrared emission (SE303), infrared (PH302) and voltage amplification (LM741), audio decoding (LM567), time delay and driving circuit (relay) parts composition. The design meets the requirements, can realize the infrared control device for drying hands to work. That meet to avoid cross infection in the people daily life requirements.
