Description
This is a CMOS single-chip 24-GHz Radar sensor module with a variable-frequency transmitter and
an ultra-high sensitivity radio wave receiver. This module has 3 sensing modes of Doppler mode,
FSKCW mode, and FMCW mode, detecting stationary or moving objects and measuring the distance.
Features
High-performance clutter cancellation function to prevent the direct leakage of transmission wave
and cancel out the unnecessary reflected wave, enabling the highly accurate motion sensing.
Automatic adjustment function for the variation of
components or the variation with temperature in transmission power, receiver gain, and other
parameters
Application
Digital Signage
Turns ON/OFF as people approach/leave. Available for outdoor use,
with excellent environmental resistance.
Observation (non-contact heart rate /respiration sensor)
Detects heart or lung movement and other small movements as Doppler shift.

Compliance Information
z Federal Communication Commission Interference Statement
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
Radar MODULE
Document Ver. 1.1
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one of the
following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate this equipment.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.

z Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20cm
between the radiator & your body.
z This device is intended only for OEM integrators under the following conditions:
1) The transmitter module may not be co-located with any other transmitter or antenna.
As long as 1 conditions above are met, further transmitter test will not be required. However,
the OEM integrator is still responsible for testing their end-product for any additional
compliance requirements required with this module installed
Document Ver. 1.1
IMPORTANT NOTE: In the event that these conditions can not be met (for example certain
laptop configurations or co-location with another transmitter), then the FCC authorization is no
longer considered valid and the FCC ID can not be used on the final product. In these
circumstances, the OEM integrator will be responsible for re-evaluating the end product
(including the transmitter) and obtaining a separate FCC authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be
installed such that 20 cm may be maintained between the antenna and users. The final end
product must be labeled in a visible area with the following: “Contains FCC ID:
O5PDPL24G11”. The grantee's FCC ID can be used only when all FCC compliance
requirements are met.
Manual Information To the End User
The OEM integrator has to be aware not to provide information to the end user regarding how
to install or remove this RF module in the user’s manual of the end product which integrates
this module.
The end user manual shall include all required regulatory information/warning as show in this
manual.
