Document Type and Number:
WIPO Patent Application WO/2013/027768
Kind Code:
A1
Abstract:
This detection circuit is provided with a converter circuit and an output circuit. The converter circuit is configured to receive an electric current signal from a pyroelectric element via an input terminal and to convert the received electric current signal into a voltage signal. The output circuit is configured to receive the voltage signal from the converter circuit, compare the size of the received voltage signal to a prescribed threshold value, and output a detection signal via an output terminal when the size of the voltage signal exceeds the prescribed threshold value. The detection signal is a one-shot pulse.
