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.

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
