Support Hi-Link LD2410S (HLK-LD2410S) 24GHz Ultra Low Power Radar Sensor

[besanur]

Describe the problem you have/What new integration you would like

• Similar to the LD2410 Module, the LD2410S is a Ultra low Power 24GHz Radar Sensor. But it works with baudrate 115200 which is the smaller problem. Since it uses a different protocol, it does not work with the current integration.

Please describe your use case for this integration and alternatives you've tried:

• Radar sensor with very low power consumption (~0.1 mA)

Additional context

• User Manual: (Communication protocol is in chapter 5) https://drive.google.com/drive/folders/1wC8KC-DaNavNbpeVouZ1HdiBzZ9YrAcg

While lacking a Sensor (haven't bought it yet due to not beeing supported in ESPhome), this external Component looks very promising! https://github.com/MrUndead1996/ld2410s-esphome

With my next order i will get some, having a native Support for such a promising Sensor (3,3V, 0.1mA Consumption) would be awesome! 💯

Thanks for your comment, I'm glad that more and more people are agreeing to this feature request. I've tested this custom component and it's worked well so far. By the way, I still need to understand the settings Distance reporting frequency and Status reporting frequency. I hope that it will soon be included in ESPHome.

Great to hear it is in a somewhat productive state useable!

By the way, I still need to understand the settings Distance reporting frequency and Status reporting frequency

In the Docs to the Device the following can be found:

Status reporting frequency: Frequency at which the sensor reports a manned/unoccupied state (0.5~ 8 Hz) Range reporting frequency: The frequency at which the sensor reports the distance to the target when it's manned (0.5~ 8 Hz)

I assume the Trigger Threshold controls the sensitivity - in your Screenshot i can neither see the reported Energy, nor a manual Threshold Setting. Is it only possible to perform an "Auto Threshold"?

Looking forward to get the thing into my hands finally 😃
