Measurement and control system of sewage treatment based on wireless sensor networks

Sewage treatment is becoming more important by the development of the worldwide industry. But bad environment of sewage farm bring wireless system a series of problem. To solve the problem, a measurement and control system by virtue of wireless mesh network is designed in this paper. In this control system, we design the sensor node based on AT89C2051 and nRF2401, which can collect needed locale information to complete sewage treatment and monitor the power of the machine to avoid accident under the condition of without cable. The experimental results show that this measurement and control system can realize the automation process of sewage treatment and has good system performance, it also provide the worker convenience monitoring.
