In this tutorial, we will learn to interface DC Voltage Sensor with Arduino and measure DC Voltages up to 25V on a 0.96″ OLED Display. Previously, we’ve made IoT based battery monitoring system and a simple voltmeter to measure the output voltages.

***************************************

This module is a 0-25 DC voltage sensing device that is based on a resistive voltage divider circuit. It reduces the input voltage signal by the factor of 5 and then generates a corresponding analog output voltage. This can be the reason why you’ll be able to measure the voltage up to 25V using the 5V analog pin of any microcontroller.

In this project, we are going to first interface the voltage sensor module with Arduino and measure the various Battery voltages. We will then use a small 0.96″ I2C OLED Display to look at the output voltage. This voltage measurement circuit is small & portable and you’ll be able to use it to detect under or over-voltage faults in electrical circuits.
