Note: This is the reference circuit which drives the PIR motion sensor. Install a noise filter for applications requiring enhanced detection reliability and noise withstanding
capability.
Differences in the specifications of electronic components to which the units are connected sometimes affect their correct operation; please check the units’
performance and reliability for each application.
Panasonic Corporation, Ltd. accepts no responsibility for damages resulting from the use of this circuit.
1) Digital output
Note: Circuit stability time: 30s max.
While the circuitry is stabilizing after the power is turned on, the sensor output
is not fixed in the “on” state or “off” state. This is true regardless of whether or
not the sensor has detected anything.

2) Analog output
Note: Circuit stability time: 45s max.
While the circuitry is stabilizing after the power is turned on, the sensor output
is not fixed in the “on” state or “off” state. This is true regardless of whether or
not the sensor has detected anything.
