What is a GPS tracker equipped with a temperature sensor?
A temperature sensor equipped with a GPS tracker is a device used to monitor temperature readings over a period of time. In cold chain logistics, it is used to record the temperature status of goods during transportation. This is achieved through integration... Internet of Things (IoT) technology This is achieved through GPS tracking technology and sensors.
How does the system work?
- Temperature sensors are typically installed in specific areas inside refrigerated trucks or trailers. The sensors then measure the temperature of that environment, usually at frequent intervals (e.g., every 5 minutes).
- The temperature reading will then be transmitted to Vehicle networking equipment The device processes the information and transmits it to the cloud platform in an easy-to-understand manner. The fleet manager receives notifications of temperature fluctuations here.
- Cartrack provides Management Platform It will safely store all temperature-related data for an extended period of time, providing fleet managers with detailed reports that display sensor readings, time, and location.
What is the best way to track temperature during transportation?
The best way to track cargo temperature during transportation is Use a remote temperature monitor Used in conjunction with a GPS tracking system. This setup offers significant advantages over traditional methods that rely on manual operation, which are prone to human error (such as using thermometers and temperature bars).
Equipped with temperature monitor GPS tracking system It provides highly accurate, real-time temperature alerts, minimizing temperature fluctuations. Some sensors are installed in different compartments of the storage unit, enabling multi-point monitoring.
They also provide location insights and historical data analytics, which help improve accountability. Furthermore, fleet managers can easily access the data through user-friendly dashboards on desktop or mobile devices.
Why is it so important to check the temperature of perishable goods during transportation?
According to reports, Hong Kong generated as much as one million tons of food waste annually in 2023.Approximately 3,200 tons of food waste are generated nationwide every day.The number is staggering.
Perishable goods such as meat and vegetables have a limited shelf life and must be delivered to retailers in optimal quality. Storing such goods at incorrect temperatures is... One of the most common food safety risks in the cold chain logistics industry This could lead to bacterial growth, resulting in spoilage and food poisoning.
The spoilage of these goods could result in significant financial losses for your shipping business and damage your company's reputation, potentially leading to product recalls and regulatory penalties.
For example, in July 2025, a certain Japanese ice cream brandImports of frozen products suspended due to excessive bacterial content.This real-life case highlights the dangers and consequences of inadequate temperature monitoring during transportation.
Which other industries would benefit most from GPS trackers equipped with temperature sensors?
For most of this article, we've discussed food, but there's also... Other industries that also require temperature monitoring systems For example, the following:
- Drug supply and vaccine distributionPharmaceuticals such as tablets, capsules, and vaccines require strict temperature control to maintain their efficacy. Any temperature fluctuations during transportation can alter the chemical structure of these products, rendering them ineffective or posing potential hazards.
- Flowers and NurseriesFlowers respond almost instantly to environmental changes. Some plants and flowers require near-freezing temperatures to survive, while others require warmer temperatures. The floriculture and nursery industry also uses temperature monitoring systems to maintain appropriate temperature ranges during transportation to preserve the quality of flowers and plants.
- Museums and Art Preservation: Artworks are typically very sensitive to temperature changes because the materials they are made of have different properties. For example, canvas (used for painting) is made of natural materials such as cotton or linen. These materials can shrink or expand with changes in temperature and humidity, causing permanent damage to the artwork. Therefore, temperature monitoring is an essential step in transporting valuable artworks.
- Funeral servicesFrom hearses to ambulances, it is crucial that these vehicles adhere to safety regulations to ensure slow decomposition, maintain dignity, and avoid health risks during transport. Temperature sensors are typically installed inside the coffin compartment of the hearse, and these vehicles are usually equipped with GPS trackers to record location and timestamps.
How to ensure proper temperature control during transportation?
Proper monitoring of perishable goods requires the collaboration of multiple technologies, such as the following:
Truck precooling
It all starts with choosing the right vehicle. Vehicles transporting refrigerated goods have their own specific specifications. Pre-cooling the storage compartments to the correct conditions before loading goods is crucial. This is why truck pre-cooling is essential for most businesses in this industry.
Temperature sensor calibration
Sensor calibration refers to the process of adjusting and setting sensors to accurately measure temperature. This is done by testing and adjusting the sensors' accuracy before installing them in the vehicle. Over time, sensors may age and give inaccurate readings, thus requiring regular checks and adjustments. Additionally, it's important to ensure sensors are placed in different areas of the cargo compartment to obtain a true picture of the storage compartment's condition.
Route planning
In the transportation of perishable goods, another crucial aspect is planning and selecting routes that shorten travel time to avoid delays that could endanger the goods. The best approach is to invest in... Route optimization software.
Real-time monitoring settings
Set up alerts for fleet managers, coordinators, dispatchers, and all relevant personnel so that they can be notified of any temperature changes or route deviations during transport.
Case Study: Supermarket Farms
Supermarket Farms supplies fresh, high-quality produce to restaurants, hotels, and catering companies in Gauteng Province, South Africa. They have over 30 years of experience in the industry.. They cannot see the driver's location, therefore they need a system that provides complete visibility to ensure there are no unnecessary detours or delays. This will help them maintain the freshness of their produce and improve efficiency.
How can we help them?
- Our GPS tracking solution This allows supermarket farms to accurately locate their drivers at any time. This helps them understand if there are delays and their causes, such as drivers idling for extended periods or deviating from their routes. If any issues cause delays, they will be notified immediately and can be resolved. They can also alert their customers, thereby reducing driver turnaround time.
- Supermarket Farm uses Our fleet management system Gain insights into drivers and vehicles to help them better manage daily operations. If a driver receives a speeding ticket, administrators can retrieve the report to verify the location of the incident.
