Oxidation Reduction Potential network sensor based on Kalman filtering

This paper introduced an oxidation reduction potential network sensor based on Kalman filtering, which based on embedded system. This sensor uses depolarization measure to dispose platinum electrode and Ag-AgCl electrode, and it can detect oxidation reduction potential (ORP) fast and exactly. Also, this senor uses wireless mesh network to realize flexible network measure. So it can arbitrary add and delete sensor node in the whole detection system. Furthermore, it has store and communication of USB and CAN bus. The ORP network sensor adopted Kalman filter algorithm to process the data measured by the ORP pole, thus the precision and reliability of measurement are enhanced.
