jet hand dryer circuit consists of five parts; the infrared transmitter circuit, infrared receive circuit, time delay circuit, hair dryer switch circuit and power circuit. In the infrared transmitter circuit, the output circuit terminal Q generates a pulse signal to control the light-emitting diode emits light pulses at, in addition, the diode from the role of protecting the infrared light emitting diode. The transistor cuts, no current flows through, Stainless Steel HandDryer in the time delay and hair dryer switch circuits, when the output Q outputs low.
