Teltonika EYE Sensor EN12830 – Certified Bluetooth temperature sensor for cold-chain monitoring
The Teltonika EYE Sensor EN12830 is a compact Bluetooth® Low Energy temperature sensor designed for certified temperature monitoring within cold-chain applications. The sensor has EN12830 certification and is intended for organizations that need to store, transport and document temperature-sensitive goods according to applicable laws and regulations.
The EYE Sensor EN12830 is used in industries where demonstrable temperature recording is essential, such as food storage, pharmaceutical logistics, medical environments and industrial facilities. With internal memory storage and certified measurement accuracy, the sensor supports compliance in audits, inspections and quality control.
Functional positioning within cold-chain and industrial monitoring
The EYE Sensor EN12830 is positioned as a certified temperature monitoring solution for cold-chain applications. The sensor measures temperatures within a range of -20 °C to +60 °C and complies with EN12830, the European standard for temperature recorders used in the transportation and storage of refrigerated and frozen goods.
Each sensor is calibrated in an ISO 17025-certified laboratory and falls within accuracy class 0.5 °C over the entire measurement range. This makes the EYE Sensor suitable for situations where measurement reliability and traceability are required.
Design and assembly for practical use
The sensor has a compact and lightweight housing with dimensions of 56.6 × 38.0 × 13.0 mm and a weight of only 18 grams. The housing is made of a food-grade plastic that meets EU and FDA guidelines for food contact, allowing the sensor to be used safely in close proximity to food.
Mounting is possible via screw points, strip, cord or tape, allowing flexible placement in refrigerated trucks, storage areas, containers and cold storage facilities. IP67 protection ensures that the sensor is resistant to dust and temporary immersion in water.
Sensor functionality and data logging
The EYE Sensor EN12830 is equipped with multiple integrated sensors and functions that contribute to reliable monitoring:
- Temperature sensor
- Humidity sensor
- Motion sensor (accelerometer)
- Magnetic detection
- Beacon ID and LED indication
- Hibernate mode
The internal memory storage provides space for 33,000 temperature records, equivalent to up to 345 days of measurement data, depending on configuration. Data can be read via the Teltonika EYE App EN12830, which is used for configuration, live scanning, data download and firmware updates.
Performance and hardware
The sensor is based on the STMicroelectronics BlueNRG-2 microcontroller and communicates via Bluetooth® 4.2 Low Energy. The transmission power is adjustable up to 8 dBm, with a typical wireless range of up to 80 meters (depending on environment and placement).
The Bluetooth connection supports multiple beacon protocols, including iBeacon, Eddystone and Teltonika protocol, enabling integration with existing IoT and telematics platforms.
Battery and deployment time
The EYE Sensor EN12830 is equipped with a non-replaceable CR2450 lithium manganese dioxide battery with a capacity of 600 mAh. The battery life depends on the set advertising interval and ambient temperature:
- \Up to 4 years at 5 s interval (default setting, 20 °C)
- Up to 2-3 years at 0 °C (depending on interval)
The battery is designed for long-term deployment without maintenance, making the sensor suitable for large-scale deployments.
