3. Installation
Install the sensor so that people will be entering from the X or Y direc-
tion shown below. If persons approch the sensor from the Z direction,
detection distance will be shortened.

Note: This is the reference circuit which drives the MP 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.
