| Much research require data acquisition system. Even some of the experiments require a data acquisition system with special specifications. In order for us can create a data acquisition system with the desired quantity and specifications, in this study we constructed a data acquisition system with general specifications as required by some research. This data acquisition system is based on microcontroller. The system can perform data acquisition of the eight input channels. By using a 10-bit ADC, the data can be displayed in the format of three digits from 0.00 volts to 9.99 volts. The system can sample the each input channel with sampling-frequency up to 1 kHz. Data representing the voltage of all channels is sent to the computer as a data logger via a USB port and received by the HyperTerminal software. This microcontroller-based system consumes power from the USB port. The system is equipped with software-tracing, so that the system can be used as a learning tool for the students. This system is expected to be developed further in order to build a data acquisition system with special specifications as required. Keywords: data acquisition system, data logger, microcontroller-based system. |
