SC1232AR3-B-001

Evaluation Kit for CMOS 24GHz Radar Sensor
 Overview

USB (micro-B)

Sensor Board“The Evaluation Kit (EVK), SC1232AR3-B-001,
provides an evaluation environment of theSocionext 24GHz Radar Sensor (SC1232AR3).
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.

 Functions
 Three detection modes :1. Entry Motion Detection :Detects a motion of target objects entrance tothe detectable area.
Detects a motion in the detection target area.
Detects distances to the detected target objects.

2. Presence Detection :3. Distance Detection : In each detection mode, the detection angle can be selected from twotypes, “Wide” and “Narrow”.
 Motion detection result (via DETOUT pin) anddistance detection result (via SPI interface) aretransmitted 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.
