Updated example code.

The calculations used in the example code should only be considered when operating at lambda levels near λ 1. Using this approximation outside the intended area of operation will result in a proportional error. The following table shows the accuracy between λ 0.750 and λ 10.119. http://bylund-automo...

Re: Knock shield stackable with audio shield?

Hello, The Knock Shield is fully stackable. The first problem you are going to run in to when stacking shields is interfering pins, I am sure you will find pins that both the Knock Shield and any other shield you stack on top of it will want to use. There is two easy ways to solve this, cut the leg ...

Re: Arduino Shield Bias Resistor

Hi Andy, thank you for the interest in our Lambda Shield for Arduino. ...the circuit seems to be missing the 100k biasing resistor to VCC and UN which is only required for the LSU4.9 and not the LSU4.2. There is a brief mention of it in the CJ125 data sheet (9.2 External elements) This is actually a...

Updated technical manual

The technical manual for the Lambda Shield has been updated with important information on how to get the most accuracy and precision out of your device. The CJ125 controller can be set in calibration mode by transmitting the SPI command (0x569D). This sets the analogue output for oxygen content to i...

Re: Lambda Shield not working!!!

Hi! Unfortunate with the C5 capacitor. Assuming that you have soldered it in place and it is working. It sounds like you are using a non original sensor. Please confirm you are using an original Bosch LSU 4.9 wideband sensor? If it is an original Bosch sensor, please let me know the pnc of it. Thank...

Re: Dual Lambda sensors

I just ordered two units from you. Thank you for your order. Today is a national holiday but the shields will be shipped out first thing tomorrow. BTW, do you have tow lambda sensors for sale? I find it hard to find here in Norway, for a reasonable price. I am aware of this problem. I can only warn...
