Gas sensor drift correction
Keep a gas-sensor array accurate for months as the sensors age.
The brief
Chemical sensors drift, so an electronic nose trained in January misreads in December. Using a three-year sensor-array recording, measure how the accuracy falls over time, and test ways to correct the drift without collecting new labelled data every month. Good looks like: a clear accuracy-against-time curve, at least two correction methods compared, and a recommendation on how often to recalibrate.
What you will build
- Load the sensor array batches in time order
- Measure accuracy as time passes
- Try drift-correction methods
- Compare methods on later batches
- Recommend a recalibration schedule
- Write a short technical note
