OmniPreSense OPS242 short range radar sensor has an easy to use API to control the output of the sensor.  
Simple commands can be used to configure the operation and output information provided by the sensor.  
Default settings are noted below.  Upon powering on the module, the default settings are used. 

 

Installation Instructions 

The OPS242 provides a complete radar module on a single board.  The coverage area or field of view (FOV) 
for the OPS242 is 76

 in the azimuth (horizontal) and elevation (vertical).  Install the OPS242 facing the 

direction of the FOV to be covered. 

 

Figure 1. OPS242 Beamwidth 

The OPS242 can generally can be placed behind most any material (plastic, glass, wood, etc.) depending 
on  thickness.    Typical  applications  will  use  plastics  such  as  ABS  or  PVC  at  3  or  6mm  thickness.    Some 
materials will block the signal and the OPS242 should not be placed behind these.  Examples of these are 
metal, concrete or brick.
