Circuit design for Wideband (Air Fuel Ratio) Bosch LSU 4.9 Oxygen Sensor Controller

We need an AFR (Air Fuel Ratio) controller for the LSU 4.9 to be designed. The circuit would need to act as the controller for this sensor with a 0-5 volts output which corresponds to the AFR values of 10-20.

The candidate would need to have worked with Wideband oxygen sensors or similar circuits, but this is not mandatory. They also would need to produce a working prototype for us. We can supply the sensor and the connector if needed. We can also provide information and datasheet on the sensor and give the details on how to test the sensor. The circuit should be as small as possible with SMD parts (1208 footprint begin the smallest).

The final design would need to include the Gerber files and the BOM list for the final production.

Get in touch with us for more details if needed.

The candidate would need to preferably be located in the UK, Europe or USA.
