Table of contents
*Micro-motions:
Stationary human (normally breathing and blinking eyes) in sitting or standing
positions (in line of sight) with no active movements for at least 30 s
–
working on
laptop/keyboard, reading book, etc.
Detection timings
•
Able to detect presence and absence (less than or equal to 1 s for presence) when
at least one moving object is present in the field of view
•
Declaration of presence/absence states is configurable (time) along with the
ability to introduce constant delays (1 to 30 s) before absence state is activated
Configurability
•
Easy configuration options via radar presence code example using UART port to
change various parameters (detection range, sensitivity).
Target platform
CSK comprising:
•
Rapid IoT connect developer kit (CYSBSYSKIT-01): based on PSoC® 6 (ARM®
Cortex®-M4F)
•
XENSIV™ BGT60TR13C
radar wing
CPU and memory
consumption
•
CPU: less than 10 percent (target platform), RAM usage: less than 100 kB, Flash:
less than 256 kB
HW interface
•
Presence information is available via UART or GPIO, with optional provision for
SPI/I
2
C as well using radar presence code example
Certifications
•
Presence solution is FCC certifiable. Recommended radar settings and test report
using an embedded reference form factor board could be provided on request.
Test conditions
•
Radar board mounted at height of 1 to 1.5 m from the ground in front-facing
orientation (radar sensor on the top side)
•
Test subject height ~1.7 m
•
Ambient temperature: 18 to 24°C
•
Relative Humidity (RH): 35 to 70 percent
Target applications
•
Homes, offices, commercial buildings

Mounting guidelines and coverage
The following mounting guidelines are recommended for the HW unit (radar wing board and rapid IoT connect
developer kit) of the CSK:
•
Mount it on a wall or tabletop at 1 to 1.5 m height from the ground.
•
Unit should be mounted in such a way that the radar wing board is in front-facing orientation (radar chip
on top side).
•
Ensure that the maximum range parameter is set properly (e.g., set the value lower than the distance to
the opposite wall in order to avoid reflection).
•
With the above conditions met, below is a representative coverage map created in open space based on
around 1.7 m test subject at standard room temperature and humidity conditions.
