Hi Jürgen, In fact, it is only the connector that has 6 pins. The sensor itself is only connected with 5 leads. The reason for this is that under a cover on the connector is a laser calibrated resistor that gives the shield its calibration data. This uses the missing pin. See the technical manual fo...

Hi Knut, Sounds like an interesting project! Sorry to disappoint you, but the Lambda Shield uses the Bosch CJ125 controller circuit. The only sensor it supports is the Bosch LSU 4.9. The easy answer is that you should order the sensor that we recommend in the technical specification of the shield. B...

Is there a analog output (0 - 5v) on this shield? I want to connect it to our dyno software as it can read analog voltates between 0 and 5 volts. Hi again Stevo, as a matter of fact the Bosch CJ125 itself has a 0-5V output, more or less. You can access it from the Analog 0 pin of the Arduino / Shie...

Stevo wrote:Thank you for the reply! As i found strange values, i ordered a new (real Bosch) sensor and now values are ok!
The other sensor was a replica i gues (also new) but quality was bad... So problem is solved!

Great to hear you got it all up and running with the proper sensor!

I'm meassuring on a 2-stoke scooter racing engine. What should be the right values if the sensor is in open air? At the moment i get 1,8 lambda +- When meassuring in exhaust i meassure 1,4 +- so it should be a bit lean. When i give more fuel it gives me 1,5 +- so what is going wrong? Hi Stevo, When...

Brilliant...this is one of the greatest lambda shield. But their a confusing schematic for connection from lambda shield pin to Arduino board pinout. I'm on my way making this wbo2 shield for fyp. Would you like to share the details. Please refer to the schematics for the pins connecting the shield...

We are happy to announce the Lambda Shield designed specifically for Arduino Uno. The purpose of this device is to give students or hobbyists the possibility to connect a high resolution wideband oxygen (O2) sensor to their projects or assignments. Adding accurate data, such as the oxygen content in...
