Dragino LTC2-Si LoRaWAN Temperature Transmitter with PT100 Probe (EU868)

The Dragino LTC2-Si is an industrial LoRaWAN temperature transmitter built for reliable monitoring across demanding environments. It reads a PT100 (Class A) temperature probe, converts the resistance value into accurate temperature measurements, and sends them over LoRaWAN to your network server and application—ideal where running sensor cables is expensive, difficult, or simply not practical.

To maintain stable measurement quality across a wide range, the device includes two internal 16-bit ADC interfaces and is factory calibrated using multiple reference resistors. The included IP68 probe is designed for insertion installations and is well suited for both indoor deployments and harsh environments where moisture and exposure are expected.

Popular industries and real-world use cases:

Building services / HVAC: Plant rooms, heating loops, supply/return lines, heat exchangers.

Industrial equipment: Process temperatures, machinery areas, electrical cabinets, storage zones.

Cold chain & warehousing: Cold rooms, temperature-sensitive storage (e.g., food logistics).

Energy & utilities: Heat distribution points, pump stations, technical cabinets/containers.

Agriculture / greenhouses: Monitoring temperature in installations, storage, or water/nutrient loops.
