TEMPERATURE MONITORING ACROSS THE SUPPLY CHAIN

Is the temperature stable throughout the journey? Was the cargo exposed to any critical changes? Can data be trusted and verified? For companies transporting temperature-sensitive goods, these questions are business-critical. 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.

THE DEMAND FOR TEMPERATURE TRACKING SOLUTIONS IS GROWING

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.

“Tracking temperature is no longer the task of producers alone – it is a shared responsibility across the entire supply chain,” says Gintarė Naraškevičiūtė, operational marketing coordinator at Teltonika. “Each link must ensure that sensitive goods remain within safe conditions.”

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 At the same time, companies face mounting pressure to prevent spoilage, comply with strict regulations, and replace outdated manual checks that are simply too prone to error.

Interestingly, monitoring is extending to goods not usually linked to temperature control. “We are seeing companies track products such as electronic components, which can be damaged by excessive heat or cold during transport,” explains Gintarė.

All of this demonstrates how broad and vital temperature visibility has become for modern logistics.

COLD-CHAIN COMPLIANT DEVICES FOR 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.”

VACCINE STORAGE SOLUTIONS USING EYE SENSORS

A Colombian company, NEFOX, specialising in IoT solutions, develops connected technologies and data platforms for multiple industries, including healthcare, 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, they 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 FMC130 model worked as a gateway to collect this data and transmit it to a cloud-based monitoring system. This solution enabled healthcare personnel to access real-time information remotely.

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.
