More of the infrared detector selling in the markets works on the same principle. But our engineer has made lots of improvement to this infrared detector. Pyroelectric element detects the presence or movement of the body and converts the output signal of the pyroelectric element into a voltage signal. Then, the voltage signal waveform will be analyzed. Thus, only when the waveform of the human body is detected through the analyzing will the detection signal be output. Although the animals would emit infrared, the infrared detector won’t touch off the alarming system because the waveform of the infrared from the animals is different from those from the human being.
