Automatic Hand Drying Controller Circuit
The operational principle of this circuit is shown in the diagram. Usually, the infrared rays emitted by the infrared emitting tube VD1 are exposed to the infrared receiver VD2, which leads the impedance of VD2 to decrease. At the same time, the fourth part of the LSE is outputing high electrical level, and the triode VT is at its deadline position. The electric relay J is in release condition with its normally open contact j 1-1 and j 1-2 disconnecting. The cold and warm air heating radiator can not work with no power supply. After people washing their hands, they will put their hands on the place between VD1 and VD2 where blocking out the infrared released from VD1, so the impedance of VD2 increases and the fourth part of LSE starts to output low electrical level, and the triode VT gets breakover, The electric relay J sucks close with its contacts power off. The cold and warm air heating radiator should be connected to power in advance and push the warm air button on the device.   (View)

Office Electric Heating Plate Automatic Switch Circuit
Office Electric Heating Plate Automatic Switch Circuit is shown as below. Based on the normal office desk electric plate heter, it equips the infrared reflection automatical switches composed of the TX50D module, can achieve the goal that automatical power up and heating whenpeople are workingon the plate, and automatic power down and stop heating when nobody there. This circuit could not only save the power, avoid the fash brought by the frequent plugs, but also can extend the life of the office electric heating plate and prevent the occurrence of accidents, it could be connected directly to the normal office electric heating plate, and is easy to produce, stable to work.   (View)
