OmniPreSense OPS242 Short Range Radar Sensor

OmniPreSense’s OPS242 is a complete short-range radar (SRR) solution that provides motion detection, speed, and direction reporting.  All radar signal processing is done on board and a simple API reports the processed data.  The OPS242 carries FCC modular approval, simplifying development and regulatory certifications for production release.  The OPS242 module can be connected to any Smart USB host (Raspberry Pi, Android device supporting OTG, PC or Mac). Additional processing and/or communication to the cloud can be performed for further data analysis or networked action.

Api Interface Specification

OmniPreSense modules have an easy to use API to control the output of the sensors. The simple commands can be used to configure the operation and output information provided by the sensor. Over time OmniPreSense will enhance the capabilities of its sensors by adding new features and functionality. These will come as new code versions which can be flashed to the board while keeping backwards compatibility.

Radar Sensor Types

OmniPreSense provides two different types of sensors, Doppler radar sensor reporting motion and speed and FMCW radar sensors reporting range. The feature differences for these sensors is shown in Table 1. The following API commands pertain to both types of sensors except for special cases. In these cases,this document will call out the special command for either a Doppler (-A) or FMCW (-B) radar.
