Temperature & Environmental Monitoring System for Fridges, Freezers & Cold Rooms

A temperature and environmental monitoring system continuously measures temperature (and humidity where required) inside fridges, freezers, cold rooms, and storage areas using IoT sensors.

The system consists of IoT Pro hardware fitted with a temperature probe or a combined temperature and humidity probe, depending on the application. Data is continuously logged and securely transmitted to a cloud platform via Cellular, LoRaWAN, or WiFi wireless connectivity.

The cloud software automatically generates alerts, dashboards, and downloadable reports, providing real-time visibility and full historical records.

Any type of fridge, freezer, or cold room can be monitored, regardless of brand, size, or age.

Even equipment that already has a built-in temperature controller or local monitoring system can be centralised into the IoT Pro platform. Standalone upright fridges, chest freezers, display fridges, and walk-in cold rooms can all be monitored using the same solution.

Yes. The system is designed for retrofit installation without operational downtime.

The IoT Pro hardware and probes are installed while the fridge, freezer, or cold room remains operational. Where required, the compressor is briefly powered down for approximately two minutes to safely connect to the compressor supply input.

Alternatively, the system can be installed in a battery-only configuration, allowing autonomous operation for 3–5 years without any electrical connection.

No. Installation does not require defrosting fridges or freezers, nor running cables across the premises.

Specialised clips are used to securely position probes inside refrigeration units without damaging surfaces. Where needed, a very small localised area can be gently heated to ensure proper adhesion, without affecting the overall temperature or stored stock.

If a fridge or cold room loses power, goes out of temperature range, or experiences any other critical issue, the system sends instant alerts via Email, WhatsApp, SMS, and automated phone call notifications.

Alerts can be delivered through multiple channels at the same time and sent to multiple users, ensuring issues are identified and acted upon immediately.

Yes. The system operates 24/7, all year round, including nights, weekends, and public holidays.

Temperature data logging, alerting, and system health monitoring run continuously. The platform also monitors itself and will notify you if any issue is detected with the monitoring or alerting process, ensuring maximum reliability at all times.

If internet or mobile connectivity is temporarily lost, the system continues to record temperature and event data internally.

Once the network is restored, all stored data is automatically uploaded to the cloud, and any relevant alarms are processed.

The system will also notify you when connectivity is lost. For maximum reliability, we typically recommend cellular connectivity with multi-network operator support, which provides the highest availability in critical environments.

Yes. The system is designed for HACCP temperature monitoring, providing continuous temperature logging, automated alerts, and downloadable reports.

All data is securely stored and can be easily accessed during audits, inspections, or internal quality reviews.

Yes. The system is specifically designed to replace manual paper-based temperature logs.

Temperature data is recorded automatically and reports can be generated and sent weekly or monthly, typically via email in Excel format, reducing human error, saving staff time, and improving audit readiness.

Yes. The system is particularly suitable for meat shops and butcheries, where strict temperature control and stock protection are critical.

It provides continuous temperature monitoring and instant alerts, acting as a reliable safeguard to protect high-value meat stock from spoilage caused by power failures, equipment faults, or human error.

Yes. The system is also ideal for seafood shops and fishmongers, where products are extremely temperature-sensitive and high in value.

Instant alerts and continuous monitoring help prevent rapid spoilage, making the system an effective insurance against losses in fresh and frozen seafood storage.

Yes. Multi-site monitoring is a core feature of the IoT Pro system.

You can monitor anything from a single fridge to hundreds of cold rooms across multiple locations from one central dashboard, accessible on mobile, tablet, or computer. Multiple users can be configured with different access permissions, making it ideal for operations, QA, and management teams.

The system alerts you early when temperatures rise above safe limits, such as refrigerated items exceeding 5 °C for extended periods or when defrosting begins.

This early warning gives you enough time to move stock, take corrective action, and fix the issue calmly, avoiding panic situations and preventing costly spoilage. In many cases, preventing a single incident can offset the entire cost of the system.

Yes, the system can be used in pharmaceutical storage and refrigerated transport environments, providing the same core monitoring, alerting, and reporting features.

However, regulatory requirements may vary depending on the application, and deployments in these environments are typically assessed on a case-by-case basis.
