HOW TO USE
1. Block diagram output circuit
1) Block diagram of the digital output circuit
2. Wiring diagram
1) Digital output
3. Timer circuit example
1) Digital output
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
4. Installation
Install the sensor so that people will be entering from the X direction
shown below.
(If persons approch the sensor from the Z direction, detection distance
will be shortened.
