TEMPERATURE MONITORING OF ELECTRONICS

INTRO

In today’s fast-paced global market, the safe transportation of electronic goods has become increasingly important, and maintaining proper temperature is one of the key factors in ensuring that safety. Sensitive electronics—ranging from lithium-based components to advanced communication modules—require constant environmental oversight to maintain their performance, longevity, and reliability.

CHALLENGE

Electronic components, including semiconductors, batteries, and capacitors, are highly vulnerable to temperature and humidity changes. Prolonged exposure to high temperatures accelerates chemical degradation, reduces insulation resistance, and can permanently damage microchips or solder joints.

At the same time, cold conditions can create condensation inside electronic devices, which may lead to brittleness or temporary malfunctions. When combined with high humidity or moisture, these conditions can cause more serious damage, such as corrosion, short circuits, or failure of the protective layers on circuit boards. According to Component Sense, the lifespan of electronic components drops by 50% for every 10°C rise in temperature above recommended levels, and excessive moisture can significantly accelerate failure modes. Without proper environmental controls, especially during long-distance transport or storage, businesses risk irreversible damage to valuable electronics.

Many companies transporting sensitive electronics still rely on manual temperature checks using thermometers or handwritten logs. Insights from comparisons of manual and automated workflows show that manual methods are slower, require more labour, and are prone to human error caused by fatigue or distraction. Sometimes checks are performed only at fixed intervals, and short-term fluctuations in temperature or humidity often go undetected. These blind spots create a serious risk for semiconductors, microchips, and lithium batteries, where even brief exposure to unsuitable conditions can lead to irreversible damage, warranty claims, and costly delays.

SOLUTION

To overcome these challenges, Teltonika ensures the safe transportation of sensitive electronics by combining EYE Sensors EN12830 with a Teltonika FMC234 tracker. Together, they provide continuous environmental oversight of electronics during delivery.

How it works - EYE Sensors' compact Bluetooth® Low Energy devices are placed directly inside packages or inside trailers. They automatically broadcast temperature and humidity data via Bluetooth. A Teltonika GPS tracker, FMC234, is installed inside the delivery vehicle or trailer, and it continuously scans for nearby EYE Sensors and receives their data. Then, the tracker transmits environmental data collected by the sensors to a remote server.

FMC234 is equipped with a high-capacity 1,000 mAh internal battery, ensuring prolonged cargo monitoring even when external power is unavailable or lost. This is especially important if the transport breaks down or cargo remains parked for longer periods, as the tracker can continue operating independently and send timely alerts about temperature changes.

EYE Sensors EN12830 measure and transmit real-time temperature readings throughout the entire journey. They provide highly precise measurements and are certified to a temperature class of ±0.5 °C, meaning the difference between the actual and measured temperatures will not exceed ±0.5 °C. With an operating range of –20 °C to +60 °C, this level of precision and continuous tracking ensures that semiconductors, lithium batteries, microchips, and other electronic components are always protected from harmful fluctuations. EYE Sensors also monitor humidity and it adds an extra layer of protection, as excessive moisture can lead to corrosion, short circuits, or degradation of sensitive components. Each sensor can also store up to 33,000 temperature measurements, which can be accessed via the Teltonika EN12830 EYE APP or integrated into the company’s chosen software platform if required. EYE APP also allows exporting logs for audits, inspections, or compliance checks, ensuring clear proof that sensitive electronics were transported under safe conditions.

To simplify operations further, every sensor comes with a unique ID, making it easy to identify and track multiple assets. For electronics shipments, this ensures that temperature and humidity records are always tied to the correct batch of semiconductors, circuit boards, or lithium batteries, preventing mix-ups, improving traceability, and maintaining full control across complex supply chains.

Both EYE Sensors and the FMC234 tracker have IP67-rated casings, making them resistant to dust and moisture. This durability ensures that the entire monitoring solution remains reliable under harsh logistics conditions. Together, these devices provide full cargo traceability, actionable insights, and a dependable audit trail that helps companies protect valuable electronics, avoid warranty claims, and maintain uninterrupted supply chains
