I have the same sensor, which I manage with an app on my iPhone. It works pretty well.
You pick on me when you wrote you want to manage it through Arduino. Since then, I want to do so.
As I have communication problem with an other Hi-Link product (HLK-LD8001B) , I've contact help desk - which is ... let see! -
LD2410C's user manual says « a PC configuration tool is provided » but I can not find any software for PC. I asked about that. The online helper said that there is kind of festival in China for now, she will contact me later.
For now, you may like to use the phone app to see your installed devices, look for "HLKradarTool"
