To realize the long-term, real-time and accurate soil carbon flux monitoring, a low-cost and low-energy soil carbon flux monitoring device integrating software and hardware is developed through combining the soil carbon flux monitoring technology with wireless sensor network technology. The central processing server software is also developed for monitoring data and estimating regional soil carbon flux. The device has the functions of sensing environmental parameters such as soil CO_(2) concentration, temperature and humidity, remote wireless network transmission of data, multi-devices cooperation, etc, and includes power supply module,perception module, communication module, display module and processor module. The experimental results show that the monitoring interface of the device is easily operated, and a good man-machine operation environment is realized. It is convenient to realize the large-scale, all-round, real-time and accurate monitoring of soil carbon flux in the regional terrestrial ecosystem.
