Abstract

In this work, detection of lead (II) ions with automatic recording and data logging system for ions based on electrochemical analysis using an ion-selective electrode and wireless communication technology in surface water are presented. The new system automatically reports lead (II) ions value, time and date in real-time. Results displays in the cellphone of a pre-determined user to a computer system for data banking and further analysis. The system consists of two main parts, a remote monitoring station, and a receiver. The monitoring station acquires the required data, and send the data to the pre-determined cellphone user or computer system in the form of short message services (SMS) using the Global Systems for Mobile communications (GSM technology). It then transmits the data using the GSM network through local telecommunications and infrastructure. The system can work correctly no matter the distance from remote stations and to the receiver. The function of the receiver (cellphone or computer) is to receive, display and databank the information. The information downloaded to the computer systems for data banking and further analysis. The comparison of the results between the results of the new system and the commercial ion water resulted in an R-squared of 0.99. The testing results obtained were compared with the corresponding reference analysis. The combination of these new technologies makes this approach more affordable and can be implemented by any persons even with little technical.
