This research work aims to explore a seismic wave monitoring device which can record and monitor the ground motion with a low-cost PC based seismic data system. The constructed device can be used for the purpose of replacing conventional analog seismic recorders. The Seismograph for Earthquake Measurement System based on Microcontroller is designed and constructed. This system is divided into three main parts: (1) Movement Sensing Amplifier (2) Data logging circuit and (3) Interfacing circuit. Movement sensing amplifier consists of the Hall Effect sensor and signal conditioning circuit. To sense the ground vibrations, a magnet and magnetic field sensor is used. In order to measure ground motions, the seismograph must remain steady when the ground moves. To obtain this steady state, the pendulum assembly is used, in which a weight is suspended from a long wire secured to a suitable wall-mounted fixing point. Typically, a magnet is attached to the weighted end of the pendulum and a magnetic field sensor is fixed to a rigid base in close proximity to the magnet. The sensor reacts to change in the strength of the magnetic field in response to earth movement. These changes are detected by electronic circuitry and suitably processed for display or recording purposes. Data logging circuit requires data acquisition and storage. The analog output of the Hall Sensor, GH-700, is connected to a microcontroller, PIC16F877A, through an ADC for digital signal conversion and data logging. An LCD display is also connected to the microcontroller to display the current measurement value. The resulting digital value is then stored in the external EEPROM. The data can be transferred to a PC with RS-232 serial communication using software."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Microcontroller"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Design and construction of Seismograph for Earthquake measurement system.pdf", "filesize": [{"value": "2736 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2736000.0, "url": {"url": "https://meral.edu.mm/record/2446/files/Design and construction of Seismograph for Earthquake measurement system.pdf"}, "version_id": "23ee0a5c-3c9e-49c6-bdb6-fac4cf884fb4"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "Proceedings of the First International Conference on Science and Engineering", "subitem_volume": "1"}]}, "item_1583103147082": {"attribute_name": "Conference papaers", "attribute_value_mlt": [{}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_supervisor(s)": []}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Hnin Thae Mon"}, {"subitem_authors_fullname": "Zaw Min Naing"}, {"subitem_authors_fullname": "Saldanha, Clement"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Other"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Other"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2009"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://uyr.uy.edu.mm/handle/123456789/320"}, "item_title": "Design and Construction of Seismograph for Earthquake Measurement System", "item_type_id": "21", "owner": "1", "path": ["1582967549708"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000002446", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "2446", "relation": {}, "relation_version_is_last": true, "title": ["Design and Construction of Seismograph for Earthquake Measurement System"], "weko_shared_id": -1}
