Re: Lambda and knock sensor on one UNO
One quick question, did you or someone else tried to connect Bosch 4.2 Lambda insted of 4.9? I have not seen the need, why use LSU 4.2 instead of LSU 4.9? http://bylund-automotive.com/images/CJ125.png According to the datasheet you need to configure the CJ125 by changing 2 resistors for it to work ...

Re: Lambda and knock sensor on one UNO
Hello Strgan, The simple answer is that you can not stack the Lambda Shield and Knock Shield on one Arduino UNO. The tricky answer is that you can probably connect the Knock Shield on the side using a breadboard, selecting the pins and functionality you require. It would definitely be possible using...

Re: Use for air readings for oxygen content higher then 20%
Hi George, I am no expert in chemistry but air does not hold more than 21% oxygen, starting from air might therefore not show any increase in oxygen. And considering that the environment need to be isolated and sealed from external influences it would be requiring a hermetically sealed enclosure fro...

Re: Use for air readings for oxygen content higher then 20%
I'm looking for an Arduino-compatible sensor for an Algae Scrubber project where I'm looking to measure the amount of O2 produced from the photosynthesis before the air exits to the atmosphere. Is this sensor something that can be used for such a project? If the oxygen content is higher than 21%, w...

Analog output for Knock Shield
Is it possible to implement an analog output for the Knock Shield? Yes, just like we did for the Lambda Shield . Here is how to connect the RC-filter to the Arduino. This is the RC-filter used in the example. To enable the output first we need to define the pin to be used. #define ANALOG_OUTPUT_PIN...

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...
