Hi Christian,
nice idea to use this project for calibration... I think, I'll use it in my car to get a little bit more power (AFR 12,5)

Project which emulates a Nernst sensor with adjustable AFR values...

moin, to log data you have to change/add the following lines: (I used Pin8 on Arduino Uno, feel free to use an other free pin) add in pin assignments: /*************************************************/ //Define pin assignments. /*************************************************/ #define SD_Card_CS ...

finally mounted the lambda sensor in the exhaust pipe of the YFM 660R Raptor, AFR gauge and the shield lambda shield. I used superseal wire connectors YFM 660R with AFR gauge http://www.bylund-automotive.com/support/images/Quad.jpg I also added a modified sketch. (function delay replaced with a time...

i don't possess a smartphone... ;-))) For a permanent installation I would prefer an Arduino Mega Mini and a little TFT Touchscreen display, perhaps coneccted with stackable headers, otherwise with 14 lines from Arduino to TFT... like this one: http://support.bylund-automotive.com/images/pingel-touc...

The power supply (a DC/DC Converter (5A)) in combination with a little PCB (30x13mm) is used to supress transients The shield will be installed in my YFM660R Raptor and later in my Corsa B. I used a schematic from VW for a T4-Bus for supression of transients. http://support.bylund-automotive.com/ima...

Shield and power supply in the box...

hi Chrstian, thanks for your reply. To use an other power supply I thought about connecting Pin X6-4 direct with the 12-volt vehicle electrical system, cause the regulated power supply for the Arduino and LambaShield is connected over a 150µH inductance (+ a bidirectional ZVS-Diode between + and -) ...

hello Christian,
np, furthermore I brigded the 2 "Diodes for the Stupid" on the Arduino and LambdaShield.. +0,7V are the result...

Hello Christian, first of all, great work.. I have a few questions: 1: is it possible, to use an external power source for the heater, for example, direct from the battery of a car and the shield and arduino from an regulated power source? 2: is it possible, to remove the serial outputs, without aff...
