Application scenarios

Widely used for environmental monitoring in offices, hospitals, factories, greenhouses, cold chains, warehouses, and residential indoor/outdoor spaces.

Application Case

◂ Pain Point▸

Lack of Centralized Monitoring: No unified system to manage temperature monitoring across 1,000+ supermarket branches.

Manual & Fragmented Processes: On-site checks delay issue detection and increase labor workload.

Food Safety & Waste Risks: Temperature deviations in refrigerated units and heating counters risk food spoilage and product loss.

Limited Real-Time Alerts: No instant alarms mean equipment failures can’t be addressed before food spoilage occurs.

◂ Solution▸

Deploy a scalable LoRaWAN® IoT temperature monitoring solution across the entire supermarket chain:

EM300-TH Temperature & Humidity Sensors: 6,000+ units deployed in refrigerated units to monitor chilled/frozen food temperatures (-18°C to +10°C), enabling fast wireless installation and compliance with food safety standards.

EM500-PT100 Platinum Temperature Sensors: 1,000+ high-precision sensors installed in heating counters, with a hidden external probe to accurately monitor hot food temperatures without contact with food or grease, enabling early anomaly detection.

Custom SaaS IoT Platform: Centralized platform for unified monitoring, real-time alarms forwarded to the customer’s existing system, and secure data storage hosted in Austria.

Result: 7,000+ sensors deployed for chain-wide unified temperature monitoring; real-time alerts prevent food waste by enabling rapid response to equipment failures; wireless, low-maintenance sensors reduce manual effort; continuous monitoring ensures consistent food quality and compliance across all stores.
