Hello there,
Do I correctly understand that you're using this board, connected to an
esp8266 development board?
With only a voltmeter testing may get tricky... Does it have a "frequency"
position? If so you could probe the fout signal to try to get a frequency
reading.
You don't need to use the nEN pin, by default the sensor is enabled

Hello Mathieu, I tried to send a message via LinkedIn, unfortunately it
costs a lot of money there, so I hope I can reach you with this.
I live on a private street where many children play a lot, especially on
Saturdays. The street is also marked that it is a dead end and private.
From the main road there is a supermarket right at the entrance to the
private road and there is usually a huge rush of cars there on Saturdays.
Unfortunately, they also get lost on the private road and take out their
shopping frenzy on the accelerator pedal there. I worry about my child and
the children who play there worriedly in moments like this.
That's why I found this here from you and had the PCB made. I also get a
level that I can read via VOUT with an ESP8266. However, I understood it to
mean that the speed can only be measured to a decent extent with FOUT.
Unfortunately I don't get a signal there at the FOUT and I don't really
know how to test it because I only have a voltmeter available.
I would like to attach a small LED matrix to the fence to show the
vehicles their speed with smiles and to display a sad smile if the speed is
too high. Hope you can still help me, even if the board is already outdated
and replaced with a new one.
Do I have to activate the board via the nEN pin and if so, how?
Does it even work with an ESP8266?
Do I have to use all PINs like you did in the video, since only PIN 4 is
specified in the Arduino Scetch?
I would be happy if you could help me, thank you very much!

hi, thx for the reply,i try to use the esp8266 wemos d1 mini, but i prepared a esp32 s2 mini and one old arduino board what i found in my basememt and hope maybe i get something to can say the pcb working.and no, my voltmeter dont have a frequency position, so yes i cant not realy say the hardware working and i can go the next steps in the code.and if i want use the nEN pin, how to conect it? to gnd or vcc? and only for few seconds or static conection?many thanks for you help!Gesendet mit der mobilen Mail AppAm 29.03.24 um 10:33 schrieb Mathieu

Leave the nen pin non connected for the moment.
If I remember correctly, the outputs are 5v so if you don't want to damage
your board you'll need a resistor divider.
Maybe as a first step you could just have a firmware running that outputs
the state of the connected fout?
