commercial hand dryer

commercial hand dryer circuit is transmitted by infrared circuit, infrared receiver circuit, the time delay circuit, hairdryer switching circuits and power supply circuits composed of five parts. In the infrared transmitter circuit, the output circuit terminal Q generates a pulse signal to control the infrared light emitting diode emits light pulses, which can play a role in the protection diode infrared light-emitting diodes. In the time delay and hair dryers switching circuit, when the output Q output low, Stainless Steel Hand Dryer the transistor is turned off, no current flows through.
