Continuous reefer-core temperature reporting every 30 seconds. Alerts fire the moment you drift outside the safe band — not the next morning, not on the invoice dispute, not when your customer rejects the shipment at the dock.
Neo-1P probe sits in the cargo core, reports every 30 seconds via BLE to the FC-201 or FC-501 in the cab, then over cellular to iMatrix Cloud.
Configurable alarm bands per load. SMS, email, push, or webhook — you pick who gets woken up at 2 a.m. and who sees the morning report.
Every temperature reading is tagged with GPS coordinates and timestamp. When a load goes out of band, you know exactly where and when.
Traditional reefer monitoring gives you a temperature reading at loading and at delivery. Anything that happens in between — a compressor that stalls on a 98°F afternoon, a door left cracked at a stop, a defrost cycle that goes long — only shows up if the cargo itself shows visible damage. By then it's too late.
iMatrix changes the economics. A probe in the cargo core and a gateway on the tractor gives you a reading every 30 seconds for the entire run. The moment the bay drifts outside your configured band, an alert fires to dispatch with the exact location and the current reading. You have time to call the driver, reroute, or pull ahead to a swap yard — before the load is compromised.
Open iMatrix Cloud and you see the cargo core temperature trended over the entire run. The yellow caution band and pink breach band are user-configured per commodity — the moment a reading enters either zone, alerts fire by SMS, email, push, or webhook. Sentry-1 door events ride the same timeline so you can see the temperature spike that came from the dock-stop with the doors open.
Neo sensors broadcast over BLE to the FC-201 or FC-501 already in the cab as the fleet's telematics gateway. One device, one cellular eSIM, one timeline — no separate Micro Gateway, no second SIM.
External probe with ISO 17025-traceable calibration. The defensible placement when your customer's QA team audits your cold chain.
Neo-1P NIST →Ambient temperature + humidity with e-ink display. For produce and floral loads where humidity matters as much as temperature.
Neo-1D →Wireless door sensor. Logs every reefer-box open/close with duration — surfaces the "door left cracked at the stop" failure mode.
Sentry-1 →Three ways to backhaul reefer-trailer sensor data to iMatrix Cloud — match the choice to whether you own the tractor, the trailer, or both, and how integrated you want your telematics + cold-chain stack.
Standard reefer fleets. The everyday FleetConnect gateway in the tractor cab. BLE aggregation for Neo-1D and Neo-1P NIST, GPS, cellular eSIM. The default choice when telematics and cold chain ride one device.
FC-201 →Industrial & remote routes. IP67, dual-CAN J1939, BLE sensor bridging, and optional Starlink (FC-501-SAT) for routes that lose cellular. One device handles ELD-equivalent telemetry and reefer monitoring.
FC-501 →Trailer-only deployments. Solar-powered tracker with BLE sensor connectivity, mounted on the trailer itself. No powered tractor required — ideal for trailer pools and drop-and-hook operations.
FC-101S →FSMA requires shippers, carriers, and receivers to document that temperature-sensitive cargo was kept at its required temperature throughout transport. iMatrix Cloud retains every probe reading, door event, and GPS ping for the life of the vehicle. One-click signed PDF exports are formatted for the way auditors actually want to consume records — per shipment, per lot, per SKU.
GTIN + lot + timestamp-correlated temperature records. When a recall comes, you know which load went where and under what conditions.
Big-box grocers, food-service distributors, and pharmaceutical shippers increasingly require traceable temperature records as part of carrier vetting. NIST-calibrated probes + continuous monitoring + signed exports gives you an answer when the question comes.
In-transit temperature is telematics — Neo sensors aggregated by the FC-201 or FC-501 in the cab. Facility-side cold storage is environmental monitoring — same Neo sensors, but aggregated by the Micro Gateway because there's no vehicle to ride on. Same catalog, different aggregator.
