AS7341 Spectral Sensor with Machine Learning for Non-Contact Temperature Monitoring in Electrolytic-Plasma Hardening

Electrolytic-plasma hardening of steel components requires reliable non-contact temperature monitoring, but traditional pyrometry is complicated by the variable emissivity of steel and the intense radiation of the plasma envelope. This work presents an approach that repurposes a compact multispectra...
