Cold Chain Monitoring
Built for extreme conditions, TUNDRA performs reliably in refrigerated transport, walk-ins, and deep-freeze storage where other sensors fail. Its IP67 enclosure, -40°C to +70°C operating range, and optimized reporting intervals ensure accurate data delivery and continuous visibility across the most demanding cold-chain applications.
Legionella Risk Prevention
TUNDRA supports compliant Legionella control programs by delivering automated water-temperature records, threshold alerts, and a complete digital audit trail. Sensor helps prevent bacterial growth before it reaches critical levels. A reliable way for hospitals, hotels, and commercial buildings to maintain regulatory standards without manual logging
Pulse Counting for Meters
Using the external digital probe, TUNDRA can operate as a pulse counter for water or utility meters. It captures every pulse reliably through edge-triggered reporting and sends data over LoRaWAN®. This enables simple remote meter reading and helps detect abnormal consumption patterns or leaks.
Pharmaceutical & Vaccine Storage
Designed for precise, reliable cold-storage measurements, TUNDRA supports pharmaceutical facilities, pharmacies, and clinics in maintaining stable temperature conditions for medicines, vaccines, and biological materials. The optional external probe enables accurate monitoring inside refrigeration units without exposing the main device to extreme cold.
Sensitive Storage Monitoring
For environments requiring tight temperature and humidity control - such as archives, digital equipment rooms, specialty ingredients, or laboratory samples - TUNDRA provides continuous, long-term monitoring. Its configurable alarms and stable LoRaWAN® connectivity help protect sensitive materials from degradation or unexpected environmental changes.

Frequently-asked questions
TUNDRA is a LoRaWAN temperature and humidity sensor designed for cold-chain and industrial monitoring. It supports temperature monitoring in refrigerators, freezers, and cold rooms, with optional external probes for measuring temperature or counting pulses from compatible equipment.
TUNDRA is designed for 15+ years of battery life, depending on configuration, reporting frequency, and operating temperature, so it suits large estates of fridges and freezers.
Yes. An optional external thermistor probe on a 1.5 m cable measures from −40°C to +105°C, so the sensor can sit outside the chamber while the probe reads inside. The device itself operates from −40°C to +70°C and is IP67-rated.
TUNDRA can store up to 3,000 data entries during connectivity interruptions, helping preserve temperature monitoring records when communication with the LoRaWAN network is temporarily unavailable. This supports more continuous monitoring and reduces the risk of missing data during network outages.
TUNDRA supports pharmacies, clinics and pharmaceutical storage for vaccines and medicines, food service cold chains, and legionella control programs that need automated water-temperature records and threshold alerts.
Yes. TUNDRA temperature and humidity data can be integrated with compatible Building Management Systems through supported LoRaWAN network and integration solutions. Depending on the system architecture, BACnet/IP or Modbus interfaces can make monitoring data available to the BMS, where temperature thresholds and alarms can be configured.
