Have you correctly modified the information below in the program so that it matches your situation?

I think that should be correct
Alright, you need to check that your programmed module is working.
That’s what @jerome was asking you.
You connect your module to the PC, open the Arduino IDE and open the ‹ Serial Monitor › window from the ‹ Tools › tab
That should allow you to follow the program’s progress through its different stages.
When I open the serial monitor I get this :
09:50:25.305 -\u003e
09:50:25.305 -\u003e ets Jan 8 2013,rst cause:4, boot mode:(3,6)
09:50:25.305 -\u003e
09:50:25.305 -\u003e wdt reset
09:50:25.305 -\u003e load 0x4010f000, len 3460, room 16

09:50:25.305 -\u003e chksum 0xcc
09:50:25.305 -\u003e load 0x3fff20
The flash didn’t go well, are you sure the selected board was the right one?
[
And by choosing ‹ D1 mini (clone) › and/or ‹ upload speed 115200 › and then reflash?
If that still doesn’t work, you’ll have to call on a friend 
When you say « reflash » do you mean « Upload »?
I have the same result as with “LOLIN
Which website did you buy your card from? Can you give us the link so we can find which one it corresponds to?

Did you successfully download the CH340G driver? Did the operation go smoothly?
Would you please, only for testing purposes, install Tasmota on it?
If yes, it’s very simple. Go to Install Tasmota
Connect your Wemos, choose the Tasmota FR version, ESP8266 module and Flash!
If everything worked, your module should now be broadcasting a WiFi access point name like Tasmota-xxxxxx
We’ll see whether it flashed or not…
It seems to have worked:
Sonoff Basic

So, it’s not a problem with drivers or hardware. We’re making little progress but we’re moving forward.
If you want to play with Tasmota, distance sensor support is native (in cm, not in %). That could validate the sensor’s operation/wiring.
The problem therefore comes either from the Arduino IDE configuration or from the program itself.
Which pins did you connect your sensor to?
Tasmota still active this morning
That’s another thing. I don’t know anything about Tasmota
I think the problem comes from the Arduino IDE and the selected board type, because the program appears to have been uploaded but doesn’t start, judging by the output in the serial monitor console.
Normally you should see a message like … connecting to 192.168.XX.XX then connecting to MQTT
Okay, I reinstalled everything
I flashed the ESP8266
Installed Arduino IDE 2.0.1
But in the library I can’t find ESP8266Wifi
There is « ESP-WiFi settings » or « ESP_WiFiManager »
Any idea?
