CJ125 error code on homemade shield

Hi Christian!, Very thanks You!!

with code correct:

now I can calculate Ip with Ip = 1000 (UA-1.5) /61.9*17 where: Ua = (ADC / 1023) right?}

Regrads,

That looks about right, except you UA need to be (ADC / 1023) * 5V.

See 4.1 in the Technical Manual.

Good luck!

ok Perfect! Very thank you again!

hi christian iam wondering to know in the lambda sheild 2.0 what kinda mosfet are in use are its still the STD30nf06lt4 or difrent kinda mosfet thanks
best regards matthew

Hi Matthew,

Lambda Shield 2 uses the same MOSFET as the original Lambda Shield.

great thanks alot

Hi Christian, I hope you are fine.
I wasn't working on this project, but now I'm back. I remember the last time it worked good. But now the UR value doesn't change even when blowing directly on the sensor.

I am using lamda shield GUI code.

Any idea what is happening?

Hi Cristian,

Besides UA being way too high and UR being too low I see another issue and that is the UB values. This indicates that you are powering your shield which a much too high voltage as you are reaching the limit of the ADC for the voltage divider used. This is one of the upgrades we did for Lambda Shield 2.

Check your supply voltage or ADC reference voltage.
