Troubleshooting
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 ...

Re: Calibration
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.

Re: Calibration
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...

Re: LEDs do not light
Good news, to use the Lambda Shield with Arduino Mega you need to reroute the SPI pins.
See example on our Instagram account.

Re: LEDs do not light
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.

Lookup table for CJ125 in V=8 amplification.
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 ...

Re: Lambda GUI not reading
If anyone runs into the same symptom we have concluded that the problem in this case was a faulty oxygen sensor.

Re: Lambda GUI not reading
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...
