A leading supermarket chain in Austria operates over 1,000 branches nationwide, managing a wide range of refrigerated and heated food areas. To ensure optimal storage conditions and prevent food damage, the retailer implemented a centralized temperature monitoring solution across all stores, supported by Sensor Network Services.
Challenges
Lack of Centralized Monitoring at Scale
Managing consistent temperature monitoring across more than 1,000 supermarket branches without a unified system.
Manual and Fragmented Processes
Reliance on on-site checks delayed issue detection and increased labor workload.
Food Safety and Waste Risks
Temperature deviations in cooling islands and heating counters risked food damage and product loss.
Limited Real-Time Alerting Capability
Without instant alarms, equipment failures could not be addressed before food spoilage occurred.
Solution
By combining a scalable IoT sensor network with a centralized SaaS platform, the solution delivers full visibility across all stores, real-time alerts for proactive maintenance, and secure, compliant data management — significantly reducing food safety risks and easing operational workload.
EM300-TH Temperature and Humidity Sensor
Over 6,000 sensors were deployed across refrigerated units to monitor chilled and frozen food temperatures from +10°C to -18°C, enabling fast, wireless installation and ensuring stable storage conditions in full compliance with food safety standards.
EM500-PT100 Platinum Temperature Sensor
More than 1,000 high-precision temperature sensors were installed in heating counters for hot food products, featuring a hidden external probe for accurate temperature monitoring without contact with food or grease, enabling early detection of anomalies and timely corrective actions.
Self-Developed IoT Platform (SaaS)
A centralized platform enabling unified monitoring, real-time alarms forwarded to the customer's existing alarm system, and secure data storage hosted in Austria.
Results
7,000+ Sensors Deployed at Scale
Enabled unified temperature monitoring and management across the entire supermarket chain.
Immediate Alerts to Prevent Food Waste
Automatic status and alarm notifications enabled rapid response to broken cooling or heating devices, preventing food damage.
Reduced Manual Effort with Near-Zero Maintenance
Wireless sensors with simple installation eliminated cabling work and minimized ongoing maintenance needs.
Consistent Food Quality Across All Stores
Continuous monitoring of cooling islands and heating counters ensured perfect conditions for food products at all times.
We're very happy with the Milesight solution. The sensors are easy to install, completely wireless, and quick to set up. Monitoring our cooling islands and heating counters has helped us keep the right conditions for our food products with almost no maintenance. Whenever there's an issue with a cooling or heating device, we're notified immediately, which allows us to react quickly and avoid food loss. Since using Milesight, we no longer worry about food waste caused by equipment failures.
