And with the same issue do you mean that is reading 1010 ADC in open air or that it is resetting the Arduino and flashing the LED's?

Re: Lambda GUI not reading
If I try to plug in the power supply when the USB is not connected, the LEDs on both boards flash about once/second, but do not stay lit. I am not sure if this is normal behavior of the board. I can replicate what you are experiencing when I have the X7 jumper and the 12V power supply connected to ...

Re: Lambda GUI not reading
UA_Optimal (λ = 1.00): 304 (λ = 1.00) UR_Optimal: 176 These values are spot on, thank you. I'm concerned that the power source could be part of the problem. I'm using a 12V, 1A wall plug. However, it takes multiple tries of plugging the jack into the board, and removing and replacing the jumper wir...

Re: Lambda GUI not reading
1. Using the code linked, this is the serial output: Measuring, CJ125: 0x28FF, UA_ADC: 1010, UR_ADC: 179, UBat_ADC: 732, Lambda: -, Oxygen: 20.95% Measuring, CJ125: 0x28FF, UA_ADC: 1011, UR_ADC: 178, UBat_ADC: 735, Lambda: -, Oxygen: 20.95% Measuring, CJ125: 0x28FF, UA_ADC: 1011, UR_ADC: 179, UBat_...

Re: Lambda GUI not reading
The O2 sensor is in normal, open air, not obstructed, etc. It was purchased from this website along with the lambda board. Very helpful, thank you for your patience. Please help me also with the following information. 1. The serial output from the example code with the set up shown in the picture. ...

Re: Lambda GUI not reading
I've added the jumper wire. The readings have not changed - the GUI outputs 20.95%, and the serial monitor output looks similar to before: STATUS,2,10495,1010,178,733 Still not getting useful readings. Thank you for the data, it is helpful. Let us analyse your readings: 2 = Heater is in temperature...

Re: Lambda GUI not reading
When you say "Never connect more than one power source at any time when using this feature", does that mean that I should not plug in the 12V power source to the board and a USB to the Arduino/computer at the same time? If so, how can I use the GUI while the sensor is powered? Sorry that ...

Re: Lambda GUI not reading
My sensor is powered by a 1Amp, 12v wall power source, and the Arduino is powered with a USB connected to the computer. The Arduino and the Bosch CJ125 controller are both powered by a common 5V. So if we do not use the built in 5V voltage regulator of the Arduino it will instead use the 5V from th...

Re: Lambda GUI not reading
Yes, the output does not change at all when breathed on. The Arduino file works just fine - but the values it reads while in open air are around 26%. This would make sense as to why the GUI isn’t outputting correctly. Do you think the sensor is reading accurately? 26% seems very high for ambient ai...
