A connected home-protection sensor combines multiple environmental signals to detect water leaks, freezing conditions and other potentially damaging events.
Every project follows the same Ryvasys Split — AI drafts the mechanical work, a named engineer reviews and owns every decision that touches safety, cost, or a regulatory limit.
Additional detail on architecture, stack and implementation specifics for this engagement.
The sensor combines multiple environmental inputs (moisture, temperature, and related signals) on a single low-power device, fusing readings on-device before firmware-level event classification decides whether conditions warrant an alert, which is then pushed through the cloud to the companion mobile app.
Sensor readings are fused and evaluated locally against classification logic tuned to distinguish real leak/freeze events from benign environmental noise, with only classified events (not continuous raw readings) driving mobile push alerts, keeping both power draw and false-alarm rate under control.
Reducing false alarms was the dominant design constraint — a single-sensor leak detector is prone to false positives from humidity or condensation, so combining multiple signal types and tuning the fusion/classification logic against real-world environmental variation was the core of the engineering work, on top of the standard low-power, always-on battery life requirements for a home safety device.
Multi-sensor fusion was chosen specifically to address the reliability weakness of single-sensor leak detectors; a home-protection device that cries wolf gets ignored or disabled, so cutting the false-alarm rate was treated as core to the product's value, not a secondary refinement.
