For digital output type, if a person keeps mov-
ing in the detection area and the detection
state persists, what kind of output appears?
What is the duration of output from the
sensor after one detection?
ON/OFF is repeatedly output.
When the detection state persists, the characteristics of the passive infrared
element cause it to repeatedly output an analog waveform as shown in the
time chart below. The output is amplified by the amplifier circuit, and when it
exceeds a certain reference level (reference voltage), detection results and
ON is output. When the reference level is not exceeded, OFF is output.
At least 10 ms.
The output from the passive infrared element will vary depending on the
speed of the detected object and the difference between the temperature of
the object and the ambient temperature.
The output from the passive infrared element is amplified by the amplifier. If
the amplified output exceeds the reference voltage, a person is regarded as
being detected and ON is output. For this reason the duration of one output
is not fixed; however, it lasts at least 10 ms due to circuit characteristics.
