AN-14 UART Interface and Arduino Support – new UART interface described along with how to interface OPS241 to Arduino.
AN-15 Simple Motion Detection Interrupt – new interrupt pin triggers when motion detection detected meeting speed, direction, and magnitude filter settings.
AN-17 Simple Counting Algorithm – explains new simple algorithm to count objects over time in the radar sensor field of view.
AN-18 Low Power Battery Operation – details how to use Hibernate mode, what levels of power consumption can be expected, and how to calculate overall system power.
AN-19 Traffic Monitor Mounting Guidelines – provides guidance on mounting OPS24x radar sensors for traffic monitoring application. Use the OPS243 Field of View Calculator to determine center point of the field of view.
Github Projects – Download projects to connect OPS241, OPS242, and OPS243 to Arduino, Raspberry Pi, display data on an LCD, or connect to an Android phone.
USB Driver – Typically the USB driver in Windows, Mac, and Linux computers will automatically connect to the OPS241 and OPS242 radar sensors. If they do not, this driver may be installed on your computer to make a connection.
ROS Package – Details for the ROS (Robot Operating System) package and support for Kinetic, Lunar, and Melodic releases.
OPS243 Field of View Calculator – input height, down angle, and in road angle to calculate the field of view center point.
