Environmental monitoring architecture designed for cold-storage and refrigeration environments.
The sensor configuration monitors ambient temperature, relative humidity (RH), and key gas-phase parameters: carbon dioxide (CO₂), ammonia (NH₃), hydrogen sulfide (H₂S), and volatile organic compounds (VOCs, including ethanol, acetone, and aldehydes).
An autonomous wireless sensor module periodically captures time-series environmental measurements in the shared air of the refrigeration chamber and transmits data to a cloud or server processing environment.
Measurements are corrected against a per-device baseline. The patented method further specifies a full multi-channel drift-compensation model.
The patented method further describes temperature correction of reaction rates using the van 't Hoff rule (Q₁₀ temperature coefficient) to account for thermal variability in cold-chain environments.
Verbatim from the FrigoSense FAQ
No. FrigoSense is an early-warning monitor, not a safety certificate. It tracks air and storage-condition signals that can help you inspect products earlier, but it does not replace labels, hygiene rules, direct inspection or laboratory testing.
No. Those require microbiological testing. FrigoSense reads indirect environmental and gas-pattern signals; it is not a pathogen detector.
Gas signals may be weak when products are sealed. In that case FrigoSense helps with temperature history and cold-environment monitoring, but it cannot see inside closed packaging.
Not by itself. The device monitors the shared air in the chamber. Product-specific conclusions require inventory context and validated data, so the dashboard keeps uncertainty visible.
It is designed primarily for refrigerator conditions. Freezers can reduce gas dynamics and affect battery behavior, so freezer use should be treated as limited monitoring, not as a validated freshness assessment.
