ABSRACT - [ Total Page(s): 1 ]This project work deals on the design and implementation of an automatic hand-dryer with display capable of drying up a wet hand inserted under its vent and goes off automatically as soon as the ands are removed. The system also incorporates a decimal counting unit that displays the temperature of the blown out air in 0C. This system is configured using an optp-coupler realized with cadmium-sulphide photocell (c.d.s) at the input. The output of the sensor is conditioned by quad-2-input schmit trigger NAND gate (74132) which serves as the control logic used to trigger a one-shot delay tha

CHAPTER ONE - [ Total Page(s): 1 ]INTRODUCTIONEngineering is concerned with goal-oriented projects. Projects that can eliminate problems like time lapse, strem and energy spent, cost and environmental dangers/hazards. This project work on the design and implementation of an automatic hand-dryer with temperature display is built to eliminate the dangers and problems associated with the manual process of hand-dryer and to display the temperature of the air used in drying the object. This project is realized with passive and active components. And it is pure hardwired in that it does not use micro-program control.1.1 GENE ... Continue Reading
