Ask our team → A Ready For Anything® building block A robust LoRaWAN temperature sensor built for the places where other sensors fail — plant rooms, cold stores, risers, and external installations. -40°C to +70°C · IP67 · 15-year battery · External probe port · Pulse counting · LoRaWAN EU868 The problem this product exists to solve Standard room sensors aren't rated for plant rooms, cold stores, or outdoor risers. Temperature extremes, condensation, and physical exposure kill them. The consequence on a BMS is a dead point — a sensor that was supposed to be monitoring a critical temperature that stopped reporting three months ago and nobody noticed until something failed. The TUNDRA is built for these environments. IP67 means it survives water immersion. The operating range of -40°C to +70°C covers every building application. The 15-year battery life means it's still reporting long after the FM contract has renewed. The external probe port means you can mount the body outside the cold environment and run the probe in — useful in pharmaceutical cold rooms where access is controlled and disturbing the temperature environment matters. Applications on site Plant room pipe monitoring — surface temperature on flow and return pipes; confirm heating system performance without opening up pipe insulation Legionella compliance — automated water temperature records, threshold alerts, and digital audit trail for hospitals, hotels, and commercial buildings; replaces manual logging Cold store monitoring — pharmaceutical, catering, or food production environments; IP67 handles condensation and wash-down environments Pulse counting — connect to a water or utility meter using the digital probe; captures pulse outputs and transmits consumption data over LoRaWAN Data logging — stores 3,000 data points (~125 days) on-device; protects against data loss during network downtime Technical Specifications Key parameters at a glance.
