DIY Wideband WBO2 AFR data logger with Arduino®

How to log data with your Arduino. We connect an SD card to the Arduino Mega and use the Lambda Shield 2 to make a DYI AFR data logger.

Lambda Shield 2 for Arduino:

SD card adapter from eBay:

Hi Christian,
nice to see your great projects progressing into more advanced units.
To people who have not tried these units i have one and love it, i run a 1.3" colour display on it and now i shall do this mode and have the ability to data log with it also.
Well done mate

What is the differences between the Lambda shield 1 et the Lambda shield 2? And what is the uptime between 2 refresh?

And can I add and an aquisition for the TPS and the revs? Thank you

Can I use that sheild as a controller to send afr data to my stand alone ecu or do I need the arduino and I want to wire up 4 sensors 1 for each piston thanks let me know

Hi
did something similar but using esp32 / M5Stack.
My requirements / solution are:
- display on unit > M5Stack gauge from library Examples
- AFR RPM and load logging > additional analog and digital input on M5Stack
- data logging > Sd card in M5 Stack
- Meter and Scroll display on Android via Bluetooth > Esp32 includes Bluetooth to "Bluetooth Electronics" App from Playstore.
Dream solution for me would be Your board V3 shrunk to M5 Shield format .... 3d print case

How this works on the arduino Uno?
Congrats!
