HLK-LD2410B FMCW 24G 24GHz Smart Human Presence Status Sensing Radar Heartbeat Sensitivity Mini Sensor Module High Detection

Product Information

Once I was done, there were absolutely no false triggers and it was able to reliable detect presence in my living room. You could try with the include of external yaml files, but what I noticed is that if you have the switch that turns on and off the connection then it will fail either 100% of the time or most of the times.

Using waves to detect objects, mmWave sensors can accurately detect a person's breathing and movements. With the power of automation, you can create a seamless and convenient environment that caters to your needs. Also is it possible to have a simpler version that tracks the presence of static and moving target ?

I am using internal BT of the Raspi4 (same device where HA is installed), and i've read no issues with that "direct" connection. During testing, I experienced frequent disconnections and stability issues with the Bluetooth integration, as many others have also reported online.

The reason to use Bluetooth is so that you can have multiple ld2410b sensors and relocate them around their esp32 hub. Because of this, It’s fair to note that I consider this approach a highly DIY solution for true Home Automation enthusiasts, it’s definitely not for everyone. Combined with radar signal processing and precise human body sensing algorithms, it realizes high-sensitivity human presence status sensing, and can identify human bodies in motion and stationary states. Recently, I tested the Apollo MSR-1 Prescence Multi-Sensor with CO2 monitoring and a bunch of other interesting features/sensors. A standard procedure is this: clean build, connect first sensor, second clean build, connect second sensor, clean build files, connect both.

Whether you need guidance on product setup, troubleshooting, or maximizing functionality, our tutorials are here to support you every step of the way. This has to be done by putting in the yaml only that sensor, that means 3 bin files total for 2 sensors that have to be flashed. Also I have about 99% uptime with the sensors, if they get disconnected is for 5 secs tops and once a day tops.

Combined with radar signal processing and accurate human body sensing algorithms, it realizes high-sensitivity human presence status sensing, and can identify human bodies in motion and stationary states. LD2410C-P" is one I don't know about, but I think it's an LD2410 with a different physical layout, 22×16 instead of 35×7, and with no BLE (? It utilizes FMCW frequency-modulated continuous wave technology to detect human targets within a defined space.The radar target entity consolidates both states, requiring both to be clear for the overall presence to be considered clear, and vice versa. Future Plans: To address the "noise" issue, I'm currently testing a multi-sensor setup combining the LD2410 sensor with a PIR sensor. Smart home devices have often been dismissed as either useless pieces of technology or expensive hobbies. Unfortunately I am not home right now to double check , but I believe that this is the version that worked.
