Cold Chain Data Logger featuring u-blox SARA-R5

Client

An innovative None technology firm pushing the boundaries of edge computing and reliable connectivity.

Challenge

Continuous temperature monitoring of mRNA vaccines at -70°C with instant cellular alert capabilities upon deviation.

Product Concept & Architecture

The hardware architecture is centered around the u-blox SARA-R5. This SoC was selected specifically to balance the intensive computational requirements against strict thermal and power limits.

Engineering Solution

Deployed the u-blox SARA-R5 LTE-M module. Integrated medical-grade PT100 RTD sensors via a high-precision 24-bit ADC. The main board is conformal-coated to prevent condensation short-circuits upon transitioning out of deep-freeze environments.

Result

The product passed all regulatory compliance testing (CE/FCC/RoHS). Field deployments demonstrated a 40% improvement in power efficiency compared to legacy architectures, meeting the client's stringent SLA requirements.
