If you are experiencing problems please follow these steps: 1. Check connections - See this video . 2. Are you using a genuine Arduino Uno? 3. Are you using a genuine Bosch LSU 4.9 sensor? 4. Are you powering the Arduino by an unstable 5V? - See this video . 5. Have you updated the Arduino Uno WiFi ...

Have we found a way to calibrate the data?

Hello.

Yes, the most common solution is to calibrate or rather verify the data in open air.

Here is a video we have made on how to get the most accuracy out of your Arduino and Lambda Shield.

Thank you.

Hallo I am new here,
is it possibel to take the O2 value on an lcd 1602 display? Sorry for my bad english
best reguards
Peter

Hello Peter,

Have you seen our YouTube video on how to connect a display to the shield?

Thank you.

Is it possible to do some probe calibration by Shield? Is there any procedure? The 2 types of calibration that I know of is the following: 1. Propane gas calibration (Not very safe): https://performancetrends.com/PDFs/A-F%20Checker.pdf 2. Free air calibration (Very safe): https://www.aga.se/sv/imag...

Good news, to use the Lambda Shield with Arduino Mega you need to reroute the SPI pins.

See example on our Instagram account.

Thank you.

Hello,

Could you please take a picture of the set up. Refer to which software you are using. And what sensor you are using.

What is the serial output?

I think we can sort this out.

Thank you.

I got a request for a lookup table when the CJ125 is in amplification V=8 compared to the standard code V=17. The V=8 mode is more useful for rich applications, the V=17 mode is more useful for lean applications. Here is a conversion table made from the LSU 4.9 data sheet for the V=8 mode: //Lambda ...

If anyone runs into the same symptom we have concluded that the problem in this case was a faulty oxygen sensor.

Please also let me know your shipping address, send it to christian@bylund-automotive.com and I will ship a replacement Lambda shield for evaluation in parallel. Thank you.

The readings are the same. I only experienced the flashing LED problem when I plug in the power jack but not the arduino. Thank you for clarifying. Using the multimeter, when reading ~1010 during operation could you please measure the voltage between the 5V pin and one of the GND pins on the Arduin...
