Four Integrated Sensors

The EYE Sensor combines four essential sensing technologies into one compact wireless device.

Integrated sensors include:

• Temperature
• Humidity
• Movement (Accelerometer)
• Magnet Detection

These sensors enable continuous monitoring of environmental conditions and asset status, making the device suitable for both indoor and outdoor IoT deployments.

Cold Chain Temperature & Humidity Monitoring

The EYE Sensor is an excellent solution for monitoring environmental conditions throughout the cold chain.

Typical applications include:

• Refrigerated transport
• Vaccine storage
• Medical refrigerators
• Food logistics
• Pharmaceutical distribution
• Cold rooms
• Warehouse climate monitoring

Real-time temperature and humidity measurements help ensure sensitive products remain within required storage conditions.

Movement & Magnet Detection

The integrated accelerometer detects movement, pitch and roll, while the built-in magnetic sensor can detect open and closed states.

Ideal use cases include:

• Trailer door monitoring
• Container door status
• Cabinet access monitoring
• Equipment movement detection
• Asset tamper detection
• Tool tracking
• Inventory monitoring

These capabilities enable instant notifications when valuable assets are moved or accessed.

Long Battery Life

Powered by an integrated 600 mAh CR2450 lithium battery, the EYE Sensor is designed for years of maintenance-free operation.

Typical battery life:

• 4+ years (default 5-second advertising interval)
• 5+ years (10-second interval)
• 7+ years (10-second interval with accelerometer disabled)

The long battery life makes the sensor ideal for large-scale deployments where minimal maintenance is essential.

Rugged IP67 Waterproof Design

The EYE Sensor features a durable IP67-rated enclosure that protects against dust and water ingress, making it suitable for demanding industrial environments.

Suitable for:

• Outdoor logistics
• Warehouses
• Construction sites
• Agriculture
• Manufacturing facilities
• Utility applications

Its compact housing also includes two mounting holes for secure installation using screws, cable ties, adhesive pads or lanyards.

Bluetooth® Connectivity

The EYE Sensor communicates using Bluetooth® Low Energy technology, allowing seamless integration with compatible Teltonika GPS trackers and gateways.

Features include:

• Bluetooth® 4.2 compliant
• Bluetooth® 5.2 certified
• Up to 80 m wireless range
• Up to 8 dBm transmission power
• iBeacon® support
• Eddystone support
• Teltonika proprietary protocol

This allows multiple sensors to operate efficiently while minimising battery consumption.

Simple Configuration with the Teltonika EYE App

The EYE Sensor can be quickly configured and managed using the Teltonika EYE mobile application.

The app allows users to:

• Configure device settings
• Change Bluetooth transmission power
• Adjust advertising intervals
• View live sensor readings
• Update firmware
• Scan nearby devices
• Configure advanced settings

This makes deployment fast and straightforward without requiring specialised equipment.

IQFLOW Cloud Integration

When paired with a compatible Teltonika GPS tracker, the EYE Sensor can transmit environmental and status data directly to IQFLOW Cloud.

IQFLOW Cloud enables:

• Live temperature monitoring
• Humidity trend reporting
• Door open/close alerts
• Movement notifications
• Cold chain compliance reporting
• Asset tracking dashboards
• Historical data logging
• Custom alarm notifications

This provides businesses with complete visibility over valuable assets and environmental conditions.
