Millimeter wave sensor HLK-LD2412S, HLK-LD2412, HLK-LD2410C Detail comparison, same hardware, different algorithms, antennas.

We put together a comparison of some recent HLK millimeter wave sensors and found that their hardware is similar.

Considering that we have DIY'd very many LD2410C, LD2412 sensors, the antenna for the LD2412S has been made simple again, and from our testing (we used it to build the L13, an improved version of the L12's sensor), they seem to perform well, with the ability to detect very small static at a distance of 5m.
