Fabrication and Development of IOT Data Logger Using ADS1256

Abstract This project presents design and fabricate ADS1256 board and a seismic signal detection system using the ADS1256 analog-to-digital converter (ADC) board and the ESP32 microcontroller. The system will interface with the ADXL335 3-axis analog output sensor to detect seismic signals in the earth, which can be indicative of earthquakes. The ADS1256 board will be designed using Eagle software and fabricated to provide high-precision analog- to-digital conversion. The ESP32 microcontroller will be programmed to read data from the ADS1256 board and send it to the Blynk server for real-time monitoring and storage. The system will utilize the high-precision ADS1256 ADC to accurately capture the seismic signals detected by the ADXL335 sensor. ADXL335 sensor is a 3-axis accelerometer that provides analog output signals proportional to the acceleration in each axis. The ESP32 microcontroller will be programmed to read the digital output from the ADS1256 ADC and transmit the data to the Blynk server using Wi-Fi connectivity. The Blynk server will provide a platform for real-time monitoring and storage of the seismic signal data. The data can be accessed remotely using the Blynk app, allowing users to monitor seismic activity in real-time. This system can be useful for earthquake detection and monitoring, providing valuable data for seismologists and researchers.
