mmWave Wars: one sensor (module) to rule them all

kiwipaul · November 19, 2023, 6:12pm

The low power version of the LD2410 is available - the LD2410S. It looks like a drop in replacement. Anyone have experience of this part?

blakadder · November 19, 2023, 8:03pm

I will have some in a few days

miguellandre · November 19, 2023, 11:06pm

I still can’t do it. I follow the configuration on the esphome page and it still doesn’t work. the sensors remain “Unknown” LD2420

**Describe the problem you have/What new integration you would like** * Similar to the [LD2410](https://esphome.io/components/sensor/ld2410.html) Module, the LD2420 is a 24GHz Radar Sensor **Please describe your use case for this integration and alternatives you've tried:** * Use LD2420 in place of LD2410 **Additional context** * Protocol information can be found at https://github.com/soubhik-khan/HLK-LD2420 * https://www.hlktech.net/index.php?id=1150

What about the detection delay between the different radar sensors, has anyone measured that? I know that FP1 was reported to be pretty bad, EP1 has an extra PIR just to rectify that, so I assume the DFRobot is also bad.

What about the various Hi-Link sensors? I am still struggling in which one to pick as they have their own positives and negatives. Detection delay is very high on my priority list, but I don’t see it reported anywhere.

ld2420 with esphome. it’s range is way more than ld2410B or LD2420C

can u share you yaml for the ld2420?
thanks

It’s no longer a external component, all ready supported by esphome

@anti-venom this thread on github contains the wiring config.

what can you say if compare ld2410 vs ld2420 for movement / presence detection?
not counting theoretical distance (8 meters are overkill as for me)

yousaf465 · January 23, 2024, 5:06am

In my testing both are similar, LD2420 lack Bluetooth, but it gains on the 3.3V power supply, simpler esphome integration, range, and in price.

Hi.
Do you know how to wire this sensor’s output into a dry contact relay so that it can act as a motion detection sensor? I tried to power an LED but it burned the LDK sensor. I ordered another one and I am trying with a digital multimeter to measure the output difference with the GND or +5V but I do not notice nothing.
My goal is to have this sensor detecting people motion wired as a door contact in an intrusion system.
thanks!

Not sure it ever possible, because it uses “hi/low” output signal, not “dry contact”

Why not? I connected standard relay (with optocoupler on input side) to my LD2410 and it works like a charm. Such relays can be widely found (aliexpress…) as “arduino relay”. LD gives 3.3V output when active (or is it 5v? I don’t remember now…) and it can easily drive an optocoupler, or LED, too. I’m not sure how you electrontech managed to burn LD with led… unless come kind of short was made (or led connected without resistor?).
