SC1233AR3-B-001

Evaluation Kit for CMOS 24GHz Radar Sensor
 Overview

USB (micro-B)

Sensor Board“The Evaluation Kit (EVK), SC1233AR3-B-001,
provides an evaluation environment of theSocionext 24GHz Radar Sensor (SC1233AR3).
The EVK consists of EVK main unit (sensor
board and interface board), accessory, andthe software package which is to be used
under the host windows OS PC connectedwith the EVK via a USB cable.

Interface Board

Evaluation Kit of SC1233AR3 Functions
 Four detection modes :1. Entry Motion Detection :FFC Cable

Detects a motion of target objects entrance tothe detectable area.
Detects a motion in the detection target area.
Senses distances to the detected target objects.
Senses 2D location of the detected target objects.

2. Presence Detection :3. Distance Detection :4. 2D Detection : Motion detection result (via DETOUT pin) anddistance detection result/ 2D detection result(via SPI interface) are transmitted to the host PC
via USB.
 GUI based evaluation software :– Detection result can graphically be plottedin the GUI application window.
– Result data can be saved to a file, and the saved
file can be loaded, and plot can be replayed.

 Measurement environment using EVKz-axis

EVKSetting : Connects the sensor board to theinterface board by a FFC cable. And connects
the interface board to the host PC withevaluation software installed by a USB cable.

USBCable

x-axisdNotes : In order to detect objects on theground, the EVK should be faced to thedetection target area, for example, placing it on
the wall or with a supporter like a tripod stand.
