Dissolved Oxygen Online Acquisition Terminal Based on Wireless Sensor Network

Dissolved oxygen (DO) is an important indicator of the water quality in the modern sewage treatment It reflects the degree of self-purification capacity of the water. In this paper, we proposed a kind of wireless sensor network-based dissolved oxygen online collection terminal. The terminal, with the core of ARM (Advanced RISC Machines) microprocessor, combines of multi-sensor data fusion technology and wireless communication technologies to achieve the distributed remote online testing of the dissolved oxygen in the sewage treatment process. It has more advantages than the traditional wired network in the occasion with cabling difficulties or relative dispersion measurement point. We establish the construction of wireless sensor network for dissolved oxygen online acquisition terminal, design acquisition terminal overall structure, and give the system software implementation flow.
