Re: NOx measurement

Hello Ilija,

NOx measurement requires a different sensor with an additional pump cell. See the NOx Shield.

Thank you.

Re: Display data freezes and sometimes returns to Bylund logo

Hello Karl, Let's see if we can figure this out, we usually do. Remove the snubber attached to the relay that switches 12v power ON/OFF to serve the Bylund shield. (Arduino has a separate power circuit with a step-down that reduces 12v to 5v.) Could you please clarify how you are powering the device...

Hello, I bought a lambda Shield kit a few hours ago in South Korea. But I just received a cancellation text message. Can you tell me the reason for the cancellation?
Hello, answered by email.

Re: Dual O2 sensors on a selector switch to single display - Possible?

Christian, O2 system in the works is a single wideband sensor, Arduino, Shield, with a single OLED .96” display. Is in ‘85 911 3.2 with SSI exhaust that has a single bung on the 1-2-3 side. Am planning to add an O2 sensor to the 4-5-6 side. As the setup is, a single OLED display works nicely (takin...

Re: No headers on shield

Hi Christian... looking at your YouTube vids, the shield you are working with has headers. Was just setting up to bench test and my shield has no headers. Pardon me as I have only a small degree of Arduino experience so until I get the system working... I may stumble around and need more assistance...

Correct? best regsrad steffen Hi Steffen, The video is based on the original Lambda Shield. Functionality is the same but there is...

Re: Lambda Shield with OLED display

Hi, I'm using the Lambda Shield with an Arduino uno wifi and an IPhone since two years. Now I like to use the OLED display SSD1306. The display works with the test-code "Hello World", but with the sketch for the Shield only the "Bylund-logo" appears on the display and nothing fu...

Re: 3.3V Usage

Hello, how can I connect a module to a 3.3-volt board like Arduino Due or ESP boards, and do I need a logic level shifter for SPI or not? Also what steps should I take for voltage levels UR and UA? Regards The Bosch CJ125 used on the Lambda Shields have 5V interfaces, why go through all that troubl...
