ABSTRACT
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 that biases a transistor switch. The transistor commutes a TRIAC (solid state relay) that switches on/off the blower connected to it. When a wet hand is inserted under the vent and blocks the line-of-sight of the sensor, the blower starts to blow automatically as long as the hands are still blocking the c.d.s, else it will stop. The seven-segment display displays the temperature of the blown out air in 0C and resets simultaneously with the switching off of the dryer.
