 OPS241-A Short-Range Radar 
OmniPreSense’s OPS241-A is complete short-range 
Radar (SRR) solution providing motion detection, 
speed,  and  direction  reporting.    All  radar  signal 
processing  is  done  on  board  and  a  simple  API 
reports  the  processed  data.    Flexible  control  over 
the  reporting  format,  sample  rate,  and  module 
power levels are provided. 
The OPS241-A module  can be connected to any Smart 
USB host (Raspberry Pi, Android device supporting OTG, 
PC or Mac) to enable an IoT sensor. Depending on the 
USB  host's  ability,  further  processing  and/or 
communication  to  the  cloud  can  be  performed  for 
further data analysis or networked action.
