This journey features the LD2412S, which shows impressive sensing capabilities.
After extended testing and use, we believe this radar has great potential. The improved antenna and new low-level algorithms have resolved some of the issues found in earlier models without the “S” suffix.
We’re proud to be among the first makers to build and share these devices.
To celebrate, we’re offering a 15% discount, and we warmly invite more people to join this fascinating exploration into millimeter-wave sensing.
One tip for working with these highly sensitive radars is to configure a “no-person delay” before triggering an “absence” event. This can help avoid awkward moments like the lights turning off too soon. A delay of 2–3 seconds often results in much more stable and reliable performance, depending on your environment.
If you’re curious about how well it performs, a reference table created by our fellow adventurer Primoslate may offer helpful insights.
