Design of Real Time Calibrated Digital Voltmeter Based on Arduino UNO
Keywords:
Arduino, ADC, Linear Regression, Voltage MeasurementAbstract
In this paper, the design and implementation of a low cost calibrated digital voltmeter based on
Arduino UNO is presented. The proposed design uses the internal 10-bit Analog to Digital
converter of Arduino UNO. Simple linear regression model is applied for the calibration of
voltmeter. However, voltage divider circuitry is being used for the enhancement of input voltage
range. This technique can be implemented to any other system where calibrated voltage
measurement is required through Arduino UNO interface.
