The sensor changes resistance when exposed to specific chemicals from mold. The system uses sophisticated data processing techniques including multiple trained models, regression algorithms, and majority voting to classify sensor readings and distinguish between different mold types. While the hardware requires advanced lab equipment to fabricate, the sensor fusion and data classification techniques are applicable to many other sensor projects. ## Full article daily.dev links to this article rather than hosting it.
