IoT Temperature Monitoring for Frozen Food Processing


In frozen food processing, strict temperature and humidity control is critical for all processing stages from raw material processing, quick freezing, packing and cold chain storage. Traditional temperature monitoring often relies on manual checks and periodic data collection, making it difficult to detect environmental changes in real time. For real-time monitoring, automated data logging and instant alerts, now Freshliance offers you Coeus Mini IoT temperature sensor.

Coeus Mini is an IoT-based temperature monitoring system. It provides end-to-end environmental visibility across frozen food processing and cold storage, helping businesses maintain stable conditions, reduce quality risks and ensure traceable food safety.

Flexible Applications & Effortless Deployment

Coeus Mini supports flexible data monitoring with built-in sensor for -20℃ ~ +60℃ and 0~100%RH and one optional external probe for -30℃~+70℃/-40℃~+85℃/-90℃~+200℃. It is ideal for diverse quick-frozen food applications, from raw material chillers, thawing areas, quick freezing areas, packaging areas to finished cold storage and even specialized cryogenic freezing processes.

Compactly designed at just 93mm*63mm*30.2mm, the main unit fits effortlessly into tight spaces across your frozen food production line. 


All-area Data at a Glance, in Real Time

This IoT temperature sensor supports seamless data to cloud via wireless 4G/WiFi/LAN connection. Choose the right connection for your application.

4G — Independent connectivity anywhere, best for locations without reliable WiFi

WiFi — Flexible wireless deployment, ideal for facilities with reliable WiFi coverage

LAN — Stable wired connectivity, best for fixed locations with stable wired networks and high connectivity reliability requirements

The cloud data will be automatically summarized, analyzed and processed. Via our dedicated mobile APP and cloud platform, you can view data in intuitive curves and detailed lists, and export reports online, enabling managers to remotely oversee conditions across multiple processing areas without frequent on-site inspections.

Diversified Alarm Channels for Quality Assurance and Compliance

In case of alarm data, local audible and visual alarms are instantly triggered, reminding on-site staff to take immediate action. More importantly, email, SMS and APP push alerts will be also sent to the designated contact persons, no matter they are at office, at home or on business.No critical alarms missed, no quality issues overlooked.


Regulatory Compliance

For frozen food processing, FDA and HACCP require precise temperature monitoring at every critical stage—from raw material receiving to freezing and cold storage. Coeus Mini is regularly calibrated before delivery, with NIST traceability. All data is time-stamped and tamper-proof, providing reliable records for quality control, traceability, and regulatory compliance. FDA 21 CFR Part 11 module is also available for cloud platform, supporting the features such as electronic signatures, audit trails, and access controls for more reliable data management.


With real-time monitoring and instant alarm notifications, Coeus Mini IoT temperature sensor helps prevent quality risks and ensure food safety throughout the entire production and storage process. If you have any questions, please feel free to contact us!
