Has anyone used the mmWave detectors?

[shykitten55]

Hi folks.

I am wanting to get one of these mmWave detectors working but it is a bit of a can of worms.

I get that that is one board and I will need to connect it to an ESP board to connect to my WiFi network.

As I use Tasmota, I would flash that then connect the detector to that board and all should work.

Operative word:  SHOULD.

But that is the overall mechanics of it - yes?

Yes, I have designed a PCB with an LD2420 module and ESP32C6 onboard recently (along with other sensors) that uses ESPHome rather than Tasmota, but it’s just as simple as any other sensor really.

I’m hoping to sell them at cost when I do a revision 2 to fix a few errors, so I’ll keep you in mind.

The modules seem to use UART more often than I2C but unless you’re trying to use multiple it doesn’t really matter — just pick some pins, connect them up between the modules, and tell Tasmota/ESPHome/Arduino library which IO pins you’ve used for which module pin.

Thanks Sophie.

There will only be 1 sensor.

I'm still stuck with exactly which one to get.

I've read a lot of articles and all the ways to connect them.   Sort of above me, but I sort of get the idea.

The last bit/part.......

What I understand is that I flash the ESP with Tasmota and set/define the pins.   Connect them as per then it should work.

I'm sort of wanting to make one myself to keep up my competency in that.

I'm just fluffed with .... the ESP board to use.

I have a HEAP of old phone chargers (EARLY ONES) with maybe 1A (2 at a push) max output and micro USB connectors.

I also have some old Node-MCU ESP-12E boards with those kind of power inputs.

All the new ones are USB-C and I don't have any SPARES of them lying around.

So the IDEA is I flash one of those older boards with the Tasmota, connect the detector to the defined pins and that's that.

I may need help checking the boards I have ARE Tasmota compatible, and if they are:  flashing them.

Oh, as the Comedy Festival is happening, I am going to be a bit busy from Friday (this) until .... 17 May I think is the last show.

After that I am not as busy.

Would you mind helping me with those parts?

Thanks.

Oh, while digging and looking, I found this:

Just wondering if it is TASMOTA compatible and would save me......  Well....   Ok, I do want to keep my skills in tune.   I just saw it while looking.

TUYA/TASMOTA.....  they are the same beast - yes?

Curious what you're using them for Sophie, I have a whole bunch of these sensors which I really should get around to playing with.... (mainly the speed one).
