Features
- The control system supports the connection of up to 18 soil chambers, making it ideal for experimental
- designs that require multiple repetitions and processes.
- It allows for long-term field monitoring without the need for human supervision, facilitating continuous,
- high-precision, and automatic unattended monitoring.
- The system automatically calculates gas flux without the need for post-processing of data. Each chamber
- can be equipped with additional sensors, such as those for measuring soil temperature and moisture.
- The system is lightweight, energy-efficient, and built for durability.
- The storage medium utilized is an SD card.
