Mod edit, topic split from another topic. I beleive the OP is addressing his / her question to @hmeijdam .
Hello, I have been working on this project close to a year for my final project in college but I have not gotten the sensor to work with the amplifier. I would really appreciate if you could be of assistance and hop on a quick fifteen minute call with me, so you could help me out with whatever challenges I’m facing
I like to contribute to this forum to give something back while learning from it myself, but I have no ambition to become a Arduino phone helpdesk.
When questions and answers are kept public in a discussion topic, everyone can benefit from it via the search function in the future. So that's where I choose to limit my contribution.
I've deleted some replies that distract from the OP's question.
So as user @hmeijdam does not answer questions on the phone.
@dayosalam
welcome to the arduino-forum.
Please post a schematic of your amplifier circuit that you are using to amplify the output-signal of the HB100 doppler Radar sensor
Here is some technical information about it
and
application-notes
If you stay here in the forum and stay public with your questions you have much more than a single person with knowledge about electronics that can answer your questions and help to solve problems.
best regards Stefan
