13/09/2012 · ELECTRONIC HAND DRYER Here is an interesting project. One can dry damp hands without using a towel by using this project. The moment we put our hands in front of the glowing bulb, we start felling hot air coming from a fan and a heater. ... This circuit is senses the presences of hands through an LDR on which the light beam falls from the bulb ...
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.
The circuit work theory This automatic hand dryer circuit is composed of power supply, infrared control circuit and hot air generation circuit, the circuit is shown in the figure 9-128. The power supply is made of power supply switch S, depressurization capacitor C1, resistor R1, bridge rectifier UR1, filter capacitor C2 and voltage stabilizing diode VS.
Infrared emission part generates a square wave signal with 50% duty cycle and 5kHz frequency by 555 circuit. And the signal drives the red launch tube to emit the infrared ray. When the hand placed under the dryers, as the hand has the reflecting effect to infrared ray, the PH302 in receiver circuit will receive the infrared signal change it into electrical

An automatic hand dryer contains a heating element and a motor which drives a squirrel cage fan. The fan exhausts air past the heating element to a downwardly-directed outlet. A base or mounting plate is adapted for flush mounting to a wall. The axis of the fan is perpendicular to the base plate and wall to which the dryer is attached. A control or sensing circuit emits signals to a detection ...
