This repository contains all code, pcb design, and verification scripts performed for the Lambda Oxygen Sensor Interface. This device uses a Bosch LSU 4.9 paired with a Bosch CJ125 to measure the oxygen content of an engine's exhaust. The value output by the device is the lambda value, which is the ratio between the stoichiometric air/fuel ratio and the air/fuel ratio measured by the sensor. The values output are between 0.65 and 1.36 and are proportional to 0 to 5V DC. A serial UART interface also outputs the lambda value, the temperature, and the voltage the sensor is being set to.
