PIR Motion Sensor PaPIRs How to Use

Technical information concerning all sensors

Block diagram output circuit

1) Digital output

2) Analog output

Wiring diagram

1) Digital output

2) Analog output

Vdd: Input power source (DC), GND: GND, Out: Output (Comparator)

Note) The output signal for the digital output type is from inside FET drain, therefore pull-down resistors are necessary. Please select an output resistor (pull-down concept) in accordance with Vout so that the output current is lower than or equal to 100μA. Use 50KΩ or more as a guide line. If the output current is more than 100μA, this may cause false alarms.

Timer circuit example

1) Digital output

2) Analog output

Note) This is the reference circuit which drives the PIR motion sensor. Install a noise fi lter for applications requiring enhanced detection reliability and noise withstanding capability.
Differences in the specifi cations 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.

Mounting direction

1.As shown in the diagram on the right, please install the sensor so that the expected trespassing direction corresponds to the X or Y direction. In some cases, moving towards or away from the sensor (parallel movement to the Z direction) may not be detected as expected sensitivity or distance.

2.*1 Please note that the horizontal and vertical field of view depends on the position of the metal tab on which the lens is mounted.
