I would like to build a WB O2 sensor. I have seen alot of the sites dedicated to a few DIY kits but would like to design one myself. What I can gather, you need 2 main things. A circuit that, when truned on, will heat the O2 sensor with a specific voltage (not to high or low), then a uC to read the voltage from the Sensor and compare with a voltage/AFR table and display the result.
Any thoughts?


By the way, I finished my tachometer/thermocouple circuit and it works great! (Crust: I did use the input capture) thanks for the help with this one guys! :roll: :D
