i am surprised and appreciating how quickly i got the response to my concerns. thank you very logical explanation for omitting the AFR and Lambda in free air measurement, i am using a brand new Bosch LSU 4.9 out of the box. i will add a note about that in the Bosch vs. generic oxygen sensor topic i ...

The Bosch sensor is functioning steady showing IP of 2.4 mA, O2 of 19.98 ? and a steady green dot
but no Lambda and no AFR figures just dashes.
is this the way it supposed to be?

how can i display the AFR and the Lambda ?

yes you are right, i am referring to the app for windows. the question might sounds silly, is the application program residing in the PC and using the serial data output of the Arduino ? Can i keep both programs running simultaneously ? if you can provide an overview of the system configuration will...

thanks for the prompt response.
i would rather try to retest with the genuine probe than disable the Diagnostics functions which are an alarm.
i will test with genuine sensor and confirm.
thanks again.

how can I display the Lambda Shield UART data logger on PC screen ?
i am already displaying the sensor status, Lambda, AFR, O2 %, heater voltage, pump current .
the display was downloaded automatically when i used how to get started Video.

i assembled the Lambda shield system and as a precaution i used first a non generic LSU 4.9 clone i bought from Germany in case there is a wiring mistake that could damage the sensor. The shield works on the bench as expected showing sensor heater worming followed by a display of all expected parame...

i have a hardware design to simulate the signal out of the LSU 4.9 for any AFR value, and working on an idea to simultaneously simulating the cell temperature. i am new to the Lambda shield group, is a hardware / software project could be interesting to the group? the design literally emulate the ph...
