PHYS-TRUST Lite

Air quality estimation on one low-cost Arduino node (MQ135 + DHT11). A Kalman filter fuses sensor physics, room mass-balance physics and an LSTM-ensemble prior, weighting each by a live trust score, with a 90% conformal uncertainty band and fault detection. Live React dashboard, local Gemma 3 explanations, 9% lower error than fixed-weight fusion.
