Automated Supermarket Cold Chain Monitoring for Food Safety Compliance

The freshness of perishable products holds paramount significance for supermarkets, as it directly impacts product quality and shelf life. In this context, the careful monitoring of both temperature and humidity cannot be ignored, as even minor fluctuations in these two parameters will accelerate spoilage. This is where BLE cold chain monitoring solutions make critical contributions. These automated sensors continuously and accurately monitor temperature and humidity levels in real-time, enabling supermarkets to ensure products remain in optimal condition while maintaining food safety compliance.

Challenge

One chain supermarket in Ghana faces a significant challenge in cold chain monitoring for temperature and humidity control. This supermarket stocks and displays a diverse array of fresh foods, each of which has strict storage requirements to preserve quality, and extend shelf-life.

Relying on manual checks conducted with handheld devices, this supermarket experiences substantial data gaps. Staff members frequently forget to record readings, and such oversight becomes more common especially during peak business hours. In addition, the numerous fridges in the store require constant cold chain monitoring and recording, which means staff members have to invest a considerable amount of time in data recording to prevent food spoilage. Despite their efforts, they are unable to detect changes within these fridges in real-time. As a result, products within an entire fridge are spoiled, leading to significant financial losses for the business.

Solution

To address these issues, automated BLE wireless temperature and humidity monitoring sensors have been introduced for comprehensive supermarket cold chain monitoring. Each refrigerator is equipped with an H4 sensor mounted on its interior wall, delivering precise environmental data in real time. These sensors transmit temperature and humidity data via a BLE-to-Wi-Fi gateway (MK107) to our client’s platform, where staff can monitor refrigerator conditions comprehensively and ensure food safety compliance.

This automated cold chain monitoring system eliminates the need for manual record-keeping. Combined with the platform, our hardware provides precise and real-time data according to specific needs. Moreover, it supports immediate alerts when refrigerator malfunctions or abnormal temperature fluctuations occur. In this way, staff members are able to monitor temperature and humidity within these fridges with ease, and take proactive intervention to safeguard product freshness, thereby significantly reducing potential financial losses while maintaining food compliance standards.

Featured Product

H4 is a BLE temperature and humidity sensor designed for precise cold chain monitoring. With a high-capacity memory capable of logging up to 60,000 data groups, it ensures comprehensive historical tracking for long-term analysis. Equipped with a long-lasting battery, the H4 offers an operational lifespan of approximately 5 years, reducing maintenance costs and downtime. Additionally, its replaceable battery design simplifies maintenance, ensuring uninterrupted performance in critical supermarket cold chain environments.

MK107 series product is a BLE to Wi-Fi gateway for supermarket monitoring systems, which works as a data bridge between BLE sensors and cloud server. It scans and collects the advertising data of the surrounding BLE devices through Bluetooth signals, and uploads the Bluetooth data packet to server through the Wi-Fi network. MK107 effectively enables a simple and effective way to monitor BLE sensors for centralized asset tracking, real-time status monitoring, and cold chain management solutions.
