Soil respiration is one of the largest and most important carbon fluxes in terrestrial ecosystems. The spatial variability of soil respiration is obvious due to the soil heterogeneity. More soil flux monitoring sites without limited monitoring radius enables to reduce uncertainty in soil respiration studies. Smart, real-time, low-cost distributed soil respiration monitoring is essential for understanding and managing rapidly changing ecosystems. PRI-8650 is a newly designed，Internet of Things (IoT) techniques based distributed soil gas flux system.
Comparing with conventional multiplexer coupled soil respiration system, each PRI-8650 is a standalone node, has full fouciton to measure soil flux, connectes via wireless networks. Simultaneous synchronous measurement enables scientists to get more valuable data.
Key Feature
- loT interconnected soil flux system
- Simultaneous synchronous measurement
- Real-time cloud data storage and backup
- Fault diagnosis and controlled remotely
