This is the reason why you can measure the voltage up to 25V using the 5V analog pin of any microcontroller. Otherwise you can do following steps for that. With the Arduino code below and when AC type is selected, the Arduino calculates TRMS value of the AC current flows through the ACS758 sensor, any DC current will not be included in the results. 0V corresponds to 0 ADC reading and 5V corresponds to 1023. Voltage measurement is the simplest task that we can perform using Arduino internal ADC. The above figure shows the 0-50V DC Voltmeter using Arduino and Seven Segment Display. 1kV DC at high power can hold a surprisingly long arc, perhaps 2 to 10cm. However, when AC+DC type is selected, the Arduino calculates TRMS value of the current that passes through the LTSR 25-NP sensor where the DC component (offset) is included in calculations. The flow chart for this project DC Current Sensor ACS712 Arduino Interfacing is shown in the figure.
