Design of simple hand dryer based on microcontroller

Overview

The hand dryer based on microcontroller control produced by this design can automatically recognize the insertion and departure of human hands. When the human hand reaches into the working range of the hand dryer, the hand dryer works, and the hand dryer stops working immediately when the hand leaves. The set time for one job is 60 seconds. Use a digital tube to display the set time of the hand dryer and display the countdown time when the hand dryer is working. When the hand dryer is not working, no time will be displayed. Use the selector switch to select the output of cold air or hot air to meet the use of different temperature weather.
