could you figured it out ?

I hope it can send you a code to test this weekend. Is the standard code working for you without problems, only that it does not display what you want?

Hello, I use googel translator. Sorry for my English. I have two questions / problems. Question 1: (Image_1) The two numbers on the display do not change. The software is "Lambda-Shield-2-GUI-Example-master" with an Arduino MEGA. Question 2: (Image_2) I don't get any values displayed on t...

same problem again with the second sensor. now it freezes again at 10,12. here is my code hope you can find the problem. This code is destroying my sensors. something is wrong. Yesterday it was working fine for like 5 minutes but once it got hot it showed me wrong values and freezes. Hello Ali, I h...

Hello Ali,

I will try to replicate the problem and see if I can find a solution.

Yes we are reading free air but it should it read 10-20? Air will not display the air fuel ratio of 10-20. Air is 20.95% oxygen, air fuel ratio of 20 (λ 1.36) is around 4-5% oxygen. The lambda sensor is measuring around 21% oxygen in clean air, the maximum value that can be displayed is λ 10 = AFR ...

Hallo,
for what version of Android is the Andriod app?
Best regards
Peter

Hello Peter, the Lambda Shield app requires Android version 9 or later.

I was wondering how difficult it might be to make the windows application cross platform, i.e. have it working on macos / Linux as well? Just a thought, not a request! Again, thanks for offering these shields and the code! Thank you DonP for the positive feedback! So far there does not seem to be a...

using lamda shield 2 GUI code the numbers on the OLED screen don't make sense to us showing 148 AFR when they should show 20 or less ??? using lamda 2 example code data logger/single band gauge with RC circuit 220uf capacitor and 1.5k resistor the gauge just shows 12.3 to 12.5 then flashes to 10.0 ...

Hello Torsten,

Great to hear everything is now working as expected! The other shield is still puzzling me so I would very much want for you to return it. I will send you an email with instructions.

Thank you.

Hello, If you want to power the Arduino from the same power source as the shield you can use the X7 jumper. This will connect the Arduino and shield through the VIN pin. Make sure you never connect two different power supplies to the DC-jacks when this jumper is set. Read more about it in the techni...
