01 / Backup
Dual archiving
Every reading is written in parallel to local microSD and encrypted cloud. If the network goes down, no data is lost.
System architecture
Three components, one infrastructure.
COLD CARE consists of a central control unit, a network of certified sensors installed in the rooms and a thermal printer for daily reports. Everything designed to withstand harsh cold environments: retail refrigeration rooms, pharmacies, food & beverage operations.
Component 01
Central control unit.
The brain of the system. Coordinates the sensor network, archives every reading and manages alarms. Connected via Wi-Fi 7, with local storage and an encrypted cloud channel.
| Processor | QUAD-core 64 bit |
| RAM | 4 GB |
| Storage | 32 GB |
| Connectivity | Wi-Fi 7 · Bluetooth 5.4 |
| Ports | 4× USB-A · 2× HDMI · 1× Ethernet RJ45 (1 Gbit) |
| Power | USB-C · 5V — 27W |
| Measurement range | −40 °C to +85 °C |
| Accuracy | 0,0625 °C |
| Protection | Waterproof IP68 and IP69K |
| Connectivity | BLE 4.0/4.2 · 2.4 GHz |
| Power | Internal lithium battery · 3.6 VDC |
| Reading rate | Programmable · default every 5 min |
Component 02
Temperature sensors.
Certified for food and pharmaceutical use, they withstand high-pressure wash cycles and the extreme temperatures of freezing rooms. They communicate with the central unit via Bluetooth Low Energy.
Component 03
Thermal printer for reports.
For those who want — or who must, by reference certification standards and HACCP plans — to keep a paper report. Automatic prints scheduled twice a day, ready for the operator's signature.
| Type | Direct thermal |
| Connectivity | RS-232 · USB 2.0 type B |
| Power | AC adapter · 24 VDC |
| Print frequency | 2 reports/day (morning · evening) |
| Maintenance | Thermal paper roll reload only |
Security & continuity
Designed to never leave you uncovered.
Redundant, encrypted, supervised architecture: if a component stops responding, the system knows it before you do.
02 / Encryption
Protected communications
All channels between sensors, central unit and cloud use standard encryption. Authenticated admin access.
03 / H24/7
Continuous surveillance
If a room or the central unit disconnects, an immediate phone notification is sent to the manager.
Automatic HACCP
An HACCP Plan where temperatures integrate automatically.
The operator just runs short checks and signs. Readings, archiving and alerts happen without manual intervention, integrated into the company HACCP manual as a digital technical annex.
- Verify system is active and there are no open alarms
- Visual check of sensors and central unit
- Daily report print (if required by the HACCP Plan)
- Assigned operator signs the report
- Archive according to the company HACCP Plan
- If an alarm triggers: verify with backup thermometer, check cooling unit, record corrective action

How we calculate
- Loss reduction: we assume 1 thermal incident every 18 months per room, 70% prevented by COLD CARE alerts, ~15% of product value lost per event.
- HACCP time: 95% of manual logging time eliminated (automatic readings and archiving).
- Fines avoided: €500/year average for minor non-conformance fines avoided thanks to digital traceability.
- System cost: indicative €1,200 base + €280/room · €240/year cloud maintenance after the first year.
