A LoRaWan based wireless data logging system was recently deployed by OTM. The system consists of:
- 1 × LoRaWan gateway (with 4G connectivity)
- 4 × Delta Ohm LR35 LoRaWan data loggers
- 10 × input channels (including temperature sensors, pyranometers, and heat flux sensors)
The system was fully integrated and configured by OTM. OTM will also provide 1.5 years of maintenance and data collection services.
The instruments are distributed in various locations of two buildings. Shown below are two important instruments of the system (left: a LoRaWan data logger; right: the LoRaWan gateway).
