Acquisition of seismic signal data requires a data acquisition (DAQ) system with high accuracy and resolution. This study focuses on developing a simultaneous seismic DAQ system with 24-bit resolution, leveraging the Message Queuing Telemetry Transport (MQTT) protocol for internet connectivity. The DAQ system consists of a master computer and slave node connected via the internet. The system design and architecture emphasize using a 24-bit resolution ADC to increase the accuracy of seismic data measurements. Extensive testing was conducted to assess the performance and reliability of the DAQ system for simultaneous seismic data acquisition. The test results show that the simultaneous seismic DAQ system has succeeded in producing data with a 24-bit resolution with a sampling rate of up to 3,366 samples per second. The MQTT communication protocol enables efficient data transfer over an internet connection, supporting simultaneous data acquisition. This research makes an important contribution to developing a simultaneous seismic DAQ system based on the Internet of Things (IoT). This system can be applied in various monitoring applications that require simultaneous acquisition of seismic data with simultaneous processing. © 2024 Author(s).
