Detection systems based on advanced technology platforms such as digital signal processing (DSP) chips and mobile phone terminals are the current developing trend of electrochemical biochemical analysis systems. The light addressable potentiometric sensor (LAPS) detection system is exploited based on DSP and mobile phone terminal. The integrated functions including LAPS output signal acquisition and processing, light source modulation signal generation, and real-time display and storage of data are realized in the proposed DSP based LAPS system. The application of this DSP-LAPS system for measuring pH values of similar buffer solutions is conducted to verify the correctness and feasibility of this system.
