Abstract
The present disclosure proposes an electronic apparatus including an attenuation element, a passive infrared (PIR) sensor, and a control circuit. The attenuation element attenuates a first infrared signal as a second infrared signal. The PIR includes a filtering element and a receiving sensor. The filtering element filters the second infrared signal as a third infrared signal, wherein a wavelength thereof ranges between 9 and 10 micrometer. When a distance between the attenuation element and a source emitting the first infrared signal is not larger than a predetermined distance, the receiving sensor outputs a first electrical signal in response to the third infrared signal, otherwise the receiving sensor outputs a second electrical signal in response to the third infrared signal. The control circuit activates the electronic apparatus according to the first electrical signal or deactivates the electronic apparatus according to the second electrical signal.
