1. Features and Applications
This motion-detection radar(Model: WDR300) operating at 24GHz ISM
band, is a Doppler radar sensor detecting even minute movement of human
or objects in real time.
It detects up to 40 m, which is longer than the other conventional sensors
and insensitive to the environmental change such as light, ambient
temperature, dust etc.
Maximum detection distance can be adjustable and be doubles by
cascading connection of the same sensors.
User friendly designs such as small form factor, single 5VDC power supply
and wired/wireless communication interfaces provides easy application of
this device.
For outdoor usage, it adopts an algorithm differentiate motions between
natural and artificial motion (especially for human).
The sensor is suitable for the energy saving application by motuion
detection.

7. Installation
Before installation, you must read “appendix 1” carefully that describes
the detection angle of the sensor.
Selecting Installation position, direction and angle.
Considering antenna as eyes and then approximately selecting the
coverage. (If there is any difficulty in installation, send us the
document and/or photograph, then we will help you to selection.)
Confirming your selection
①Set to maximum sensitivity (refer “5.2” if this manual)
②Check your coverage selection.
③Check your wiring.(refer chapter 6)
④Wait about 2 seconds after power on.
⑤Check the blind spots. – If not enough change the direction
and/or sensitivity.

Radome is the case of antenna part. The sensitivity may be greatly
degraded unless properly designed.

Antenna consist of 2 parts; Tx and rx. They are same1x3 patch type
having 60 degree horizontal half-power beam width and 35 degree
vertical half-power beam width.
Horizontal/vertical are not absolute and can be rotated for your own
purpose.
The beam-shape is fan shaped but at short range the coverage angle
become wider. The actual detection profile is similar to a balloon. Note
there is a trade-off between near blind spots and maximum detection
range. This trade-off becomes more serious when the installation height
becomes higher.
