Sensor page: 10.525GHz Doppler Effect Microwave Motion Sensor SKU: CQRSENWB01 - CQRobot-Wiki
Hello, I am working on a project and am kind of lost. It is supposed to be a speed detector for baseball. I have an arduino uno r3 and a CQRobot 10.525 GHz Doppler effect sensor. Any help with coding and
how to get readings from it would be appreciated, I don’t have any prior experience with arduino projects.
Please read and follow the directions in the "How to get the best out of this forum" post, linked at the head of every forum topic. It explains what information you need to provide to get informed help.
Obviously, you need to post a link to the sensor data sheet or product page.
Usually the seller or manufacturer provides a getting started guide and example code, which you should study carefully and do your best to implement.
This is a great place to start.

Hi, @forrest02
Welcome to the forum.
If you read the document that you posted.
The sensor is Doppler, but only outputs if motion is detected.
You need to measure Doppler frequency shift and that sensor seems to only output a HIGH if motion is detected.
Also it has a very broad sensing angle, if you are measuring an objects speed, you will need a relatively narrow angle.
