Indoor Humidity Predictor blends computer-vision, pressure analytics, touch latency and ambient-light scattering to give you an instant picture of the moisture in the air—no extra hardware required.
Why humidity matters
- Dry air (under 40 % RH) can dehydrate skin, irritate airways, warp guitars and crack wooden furniture.
- Humid air (over 60 % RH) encourages mold, dust-mites and sluggish thinking.
How it works
- Camera Fog Test – our most accurate method
- A micro-mist is briefly introduced to the lens; a neural network times dissipation to infer dew-point.
- Barometric Pressure Trends
- Uses the built-in barometer plus local weather trends for a coarse baseline.
- Touchscreen Response
--Dry air lowers skin capacitance; your tap-reaction profile helps refine estimates.
-Ambient-Light Scattering
- Measures Rayleigh scatter to detect airborne particulate moisture.
Each sensor scores independently; our fusion engine ranks confidence in real time, then delivers a single percentage along with a simple verdict—Dry, Ideal or Humid—so you know exactly what to do next.
