Wetland multi parameter wireless multi-point monitoring system based on LabView

In order to realize real-time monitoring of wetland environment, a wireless monitoring system based on LabView, STM32 and wireless transmission module is developed. The system adopts STM32 to collect pH value, dissolved oxygen, ammonia nitrogen and other multi parameters in water quality, and transmits them to terminal node through multi-point wireless measurement network. The terminal node transmits data to LabView of monitoring center through RS-485 serial port to realize the display of upper computer data. The test results show that the system has high stability, reliability and expansibility, and can be applied to wetland, sewage treatment plant and other large water quality monitoring needs.
