Some physical parameter that often be investigated are ground movement and changing inclination of the land. Those phenomena are the key points on predicting the occurrence of disaster especially landslide and volcano eruption. One of the method that can be used to prevent the loss of life caused by the disasters is by observing the movement and the change of the slope of inclination at the prone areas using tilt sensor. The increase of possibility of disaster occurrence is reflected on the increase of tilt sensor usage. Therefore, a simple system for testing the performance of a tilt sensor is required. A simple and low cost tilt calibrator has been made by using a stepper motor that is controlled by AVR ATMega8 in which its data and control parameter would be displayed in a 16×2 LCD. The system calibrator was developed to test the readings of the slope from the MMA8451Q accelerometer sensor by moving forward from 0° to 90° and then backward from 90° to 0°. The hysteresis curves of this sensor for each axis have been investigated. Small hysteresis values have been found at the results of MMA8451Q sensor measurement which mean that the sensor has a high degree of stability.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1063/1.4947411[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
