Human Sensor L12 For Home Assistant By SCREEK (HLK-LD2412, ESP32-C3, ESPHome)

Description

The HLK-LD2412 has some nice enhancements to the LD2410 (we use it for a range of our radars, such as the 1U, 1WX, 1MS, etc.):
Better antenna design
Larger coverage area
Better static capability
The included light module is also better at performing in low light.
Up to 13 gate detections means you can fine-tune the sensitivity of certain gates by filtering them.
With three resolutions (0.25m, 0.5m, 0.75m), compared to the LD2410, there are 0.5m more.
In our tests, we also found some shortcomings:
The shortest detection distance showed a large numerical error, and the HLK developers explained that the ranging aspect of the radar was weakened in favour of enhanced overall radar detection.
This is a new adventure and we invite more people to join it. We have assembled the Human Sensor L12 with the ESP32-C3 and the LD2412, we have tweaked the firmware, and through the co-operation with the HLK developers and after almost 2 months of internal testing, we now have the opportunity to invite people to join this new adventure.
