In this study, a nano sensor system was developed to control the quality of the aquaculture water. The analog signals received from the sensor electrodes were converted to the binary digital signals by an Analog to Digitals Converter (ADC). The signals adjustment was concurrently processed with the signals conversion to ensure the most accurate results were obtained. The controlled firmware for these processes was programmed on the Arduino IDE environment with C or C++ languages for the ADC MCP3208 connected to the ATMega 2560 processor. The output signals from the sensors could be converted from analog to digital form, which could then be processed by the microcontrollers or microprocessors. The two-point calibration method was employed to enhance the accuracy of the sensor output signal and minimized the deviation during the conversion from analog to digital signals.
