**********************************************************
Do you want to learn how to make a Dc Voltmeter using a 0-25v Voltage sensor? Then watch this tutorial from start to the very end. Because In this Episode you will learn how to read voltages ranging from 0.02445 to 25volts and then how to modify this sensor to read voltages ranging from 0.02445 to 319.372 Volts or even more let's say 1000 volts. This project can be used for monitoring the Solar panels, Batteries, ac line voltages, and so on. Let's get started.
This is the Voltage sensor Module that we will be using today, This Module is capable of measuring the voltages ranging from 0.02445v to 25volts dc. later in the calculations i will tell you how to modify this sensor to read higher voltages, but for now let's talk about the voltages ranging from .02445 to 25volts.
As you can see on one side we have a block terminal, this is where we connect the voltage and ground wires coming from a battery , solar panel or any other source. The Voltage wire is connected with the vcc terminal and the ground is connected with the gnd terminal.
On the other side we have three male headers labeled as + , s and -.
the s pin of the sensor module is connected with the analog pin of the arduino uno or mega and the - pin is connected with ground of the Arduino. while the + pin is not connected.
Arduino will be used for programming. Or if you want you can also use mega.
