【 摘 要 】

The electrochemical sensor exploits current or voltage on the electrodes when the chemical reaction occurs between the sensitive part of the electrode and the heavy metal ion detected. The output of current or voltage changes corresponds to the amount of ion concentration of heavy metal in water. This research aims to develop signal processing system using raspberry PI as a supporting electronic scheme of electrochemical sensor to detect and analize heavy metal pollutant. The system contains of potentiostat, signal conditioning and data acquisition schemes. This research covers the activities of the design and development of Raspberry Pi based supporting electronic scheme, PCB and the electronic components, as well as the software program for the measurement of signal input from the electrochemical sensor. The performance of K500 system developed in the research is a little bit lower than that of the system published by another researcher. Despite its performance, this system costs only $45 cheaper than previous system that costs $100. For full version, i.e. including Raspberry Pi as a server, the K500 system with the dimension of 110x90x70 mm costs only $70, cheaper than the other system using laptop computer as a server that costs $60 without its server.
