1. A welding helmet, comprising:
an analog optical sensor configured to detect incoming light and output a signal indicative of a light intensity level; and
an auto-darkening faceplate; and
a control circuit configured to:
receive the signal from the analog optical sensor, and
record a welding time based on the signal from the analog optical sensor and a configured light level, wherein the welding time corresponds to a duration of time the light intensity level indicated by the analog optical sensor exceeds the configured light level, and wherein the configured light level is higher than a threshold light level where the auto-darkening faceplate transitions between a reduced shaded state and a highly shaded state.
