HUMIDITY ALERTS DON'T PREDICT MOLD.
Many smart home sensors use a simple humidity threshold to flag mold risk. In practice, mold growth depends on time, temperature, and surfaces, not just a single number. For instance, a brief spike after a long shower is very different from weeks of dampness in a cold corner.
Newer models look at how long conditions can support growth, providing earlier and more useful context. Learn more →
Most humidity sensors still work on logic that’s about 50 years old. They ask one simple question: Is humidity above 60% right now?
