Cold Room Temperature Monitoring For Hong Seafood


Project Summary

Keeping the right temperatures for seafood, especially prawns, is essential for business success. Hong Seafood, a seafood supplier, maintains the integrity of its goods to ensure that quality is never compromised. To achieve this, they use cold rooms to store their goods at optimal temperature conditions.

In the past, they relied on a built-in temperature monitoring system in their cold rooms to maintain these ideal conditions. But, the system reached a stage where it could no longer support them. Hong Seafood saw the need to invest in a new external temperature monitoring system. This aligns with their dedication to ensuring the highest product quality and food safety for customers. The business knew that a new temperature monitoring system could enhance business operations. This includes improving staff efficiency and addressing cold room temperature deviations more quickly. It also helps with a smooth auditing process by the Singapore Food Agency (SFA). SFA audits enforce food safety standards, including the requirement for businesses to store goods at appropriate temperatures. The SFA will need the business to provide relevant temperature data records of the cold room.

These are some of the reasons why Hong Seafood requires this technology for the business.

Company Profile


Hong Seafood is a leading seafood supplier located in Singapore. Established in 1986, the company specializes in supplying prawn-based goods. While their primary focus is on prawns, they also offer other seafood products. This helps them to cater to the diverse needs of its customers. Their clientele includes restaurants, hawkers, and hotels. Hong Seafood currently holds the following certifications:

  • Marine Stewardship Council (MSC) & Aquaculture Stewardship Council (ASC) chain of custody certification

  • Industry Organization for Standardization (ISO) 9001:2015 & 22000:2018

  • BizSAFE level 3 certification

These certifications, coupled with their service-oriented approach, are the reasons why their customers consistently choose to return or stay with them for many years.

MWI Product Used

  • ThermoCare Temperature Monitoring Solution
  • OpenEnergyMonitor emonTH Temperature & Humidity Sensor
  • OpenEnergyMonitor emonPi

The Solution


Hong Seafood recognized the ThermoCare product as a valuable tool for monitoring their cold room and receiving alerts about deviations from optimal temperatures. This product comprises LORAWAN sensors, a gateway, cloud server, and a web application. The installation for the devices is straightforward, and the system itself is user-friendly.

Multiple sensors are placed in the cold room. These sensors will monitor temperatures and automatically capture temperature data. The data is then sent to the web application. The web application enables Hong Seafood to remotely monitor cold room temperatures. It also allows them to extract relevant temperature data for submission to SFA auditors during audits.

One of the primary reasons for Hong Seafood’s investment in this product is receiving temperature threshold breach alerts on their phones through Telegram. This feature significantly improves over their previous temperature monitoring system, which limited alerts to the control panel. This not only saves time but also enables prompt corrective actions, like calling for cold room servicing to maintain optimal temperature conditions for their goods.


With the ThermoCare product, Hong Seafood can:

  1. Remotely monitor and ensure optimal temperature range and functionality of their cold room.

  2. Receive alert notifications for temperature threshold breaches

  3. Reduce the amount of time needed to resolve the threshold breaches

  4. Ensure that they store their goods within the temperature range set by the SFA

  5. Ensure a smooth flow of the auditing process with automated temperature data recording and providing auditors with relevant temperature data records
