Hi cleggy, I know little about lambda sensors but feel I should do so I've just been googling and found this, see here for a sensor interface design: http://speeduino.com/forum/viewtopic.php?f=15&t=2067&sid=ff1ad55d2a189c5d11689964fc23f11a
The circuit uses a custom instrumentation amplifier and pwm heater controled by microprocesor.
kind regards, David
