[0002] An infrared detector is a detector that works by detecting infrared rays emitted by the human body. In the infrared detector, the thermoelectric element detects the presence or movement of the human body and converts the output signal of the thermoelectric element into a voltage signal.

Therefore, an adjustable infrared detector is proposed. Utility Model Content
