TEMPERATURE MONITORING ACROSS THE SUPPLY CHAIN WITH BLUETOOTH® SENSORS

For companies transporting temperature-sensitive goods, reliable temperature data is essential for ensuring product quality, meeting regulations, and protecting reputation. With more companies requiring accurate insights, Bluetooth® sensors have become indispensable in logistics, offering real-time monitoring across multiple industries.

WHAT SHOULD COMPANIES CONSIDER IN COLD CHAIN OPERATIONS?

A cold chain is a temperature-controlled supply chain designed to keep sensitive goods within required temperature ranges during storage and transportation.

When managing these goods, it is essential for companies to know:

- Is the temperature stable throughout the journey?

- Was the cargo exposed to any critical changes?

- Can temperature and location data be trusted and verified?

This level of visibility can be achieved with telematics devices and Bluetooth® sensors for continuous temperature and location monitoring.

WHY RELIABLE TEMPERATURE MONITORING MATTERS?

Global food and beverage logistics is projected to reach $6.8 trillion by 2031, while pharmaceutical logistics is expected to grow to $154 billion by 2033. These figures reflect the vast scale of shipments where even a small temperature deviation can cause significant losses or compromise product safety.

Maintaining the right conditions is a shared responsibility across the entire supply chain, with every participant expected to help ensure that temperature-sensitive goods remain within safe limits.

The rising demand for fresh food and the rapid growth of e-commerce are further increasing the need for dependable monitoring. At the same time, companies face pressure to prevent spoilage, comply with strict regulations, and replace outdated manual checks that are prone to human error.

Temperature monitoring is also expanding beyond products traditionally associated with the cold chain. Electronic components, for example, can be damaged by excessive heat or cold during transportation. This makes temperature monitoring in electronics logistics increasingly important for protecting sensitive cargo throughout the journey.

TELTONIKA‘S SOLUTION FOR COLD CHAIN TEMPERATURE MONITORING

To meet the growing demand for reliable temperature-sensitive product monitoring, Teltonika’s telematics division developed a line of Bluetooth EYE Sensors, including standard, ATEX-certified, and EN12830-certified.

“For temperature monitoring, EYE Sensor EN12830 is the best choice,” says Donatas Urbonas, project coordinator at Teltonika. “It covers a wide range of use cases in both transportation and storage, making it especially valuable for clients working with perishable goods.”

This device was created to meet standardised requirements in cold chain logistics, particularly in Europe’s food sector. It provides additional benefits over the standard model, such as a temperature sensor calibrated in an ISO 17025-certified laboratory with 0.5°C accuracy, internal memory for up to 345 days of logs, and a food-grade casing compliant with European and US Food and Drug Administration regulations.

“The certification process is not only about firmware or software,” Donatas explains. “The devices are also tested for vibration, shock, and electromagnetic compatibility to ensure they remain reliable in harsh transport environments.”

EN12830 compliance also simplifies audits, as clients can download logged data when required. Combined with real-time monitoring of temperature, humidity, and environmental changes, EYE Sensors help companies prevent spoilage by reacting before conditions reach damaging levels.

“Installation is extremely simple – no wiring is needed,” Donatas points out. “You can attach the device with a zip tie, tape, or screws and it is ready to use. It can also be delivered preconfigured or placed in hibernation mode to save battery. This way, clients can integrate them with our fleet management devices straight out of the box, without additional effort.”

KEY BENEFITS OF EYE SENSOR EN12830:

• Certified for cold chain use

• 0.5°C accuracy with ISO 17025 calibration

• Up to 345 days of internal data logging

• Food-grade casing

• Real-time temperature and humidity monitoring

• Simple wireless installation and fleet device integration

VACCINE TEMPERATURE MONITORING WITH TELTONIKA EYE SENSORS: A SUCCESS STORY

A Colombian company, NEFOX, specialising in IoT solutions, develops connected technologies and data platforms for multiple industries, including healthcare. The company needed a reliable real-time monitoring solution to ensure vaccines were stored under optimal conditions and to eliminate the risk of unnoticed temperature deviations in refrigerators and transport units.

To safeguard vaccine quality and prevent spoilage, NEFOX implemented Teltonika’s FMC130 GPS tracker together with EYE Sensors. The Bluetooth® Low Energy (BLE) devices were placed inside refrigeration units to continuously monitor temperature, while the FMC130

worked as a gateway to collect this data and transmit it to a cloud-based monitoring system.

As a result, the company achieved continuous automated temperature monitoring, significantly reducing the risk of vaccine spoilage. It provided peace of mind by helping maintain the integrity of temperature-sensitive pharmaceuticals.

This approach can also be applied more broadly to the distribution of pharmaceuticals, where maintaining stable temperature conditions and having access to reliable monitoring data are essential throughout transportation.

WHAT CAN TELEMATICS SERVICE PROVIDERS LEARN FROM THIS SUCCESS STORY?

• Combine GPS trackers and Bluetooth® sensors for end-to-end monitoring

• Use vehicle trackers as a gateway to transmit temperature data to cloud platforms

• Offer remote monitoring without complex sensor wiring

• Extend fleet management solutions to temperature-sensitive cargo
