OPS241 Radar

Project description

OmniPreSense OPS241 Radar driver (Version 0.0.4)

OPS241a

A library and tool to configure and use the OmniPreSense OPS241 Radar unit.

The OPS241-A is complete short-range radar sensor 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 is provided.

This tool makes use of the API to configure the radar unit and to display dataflow from it.

Library usage

This library provides OPS241Radar class:

from ops241.radar import OPS241Radar

with OPS241Radar() as radar:
    print(radar.get_module_information())
    while True:
        data = radar.read()
        if len(data) > 0:
            print(data)

ops241-radar usage
