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.
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
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.
