Arduino Voltage. For measuring the voltage a voltage divider circuit is implemented using a 10KΩ and a 22KΩ Resistor. This means that it will map input voltages from 0 to 5V into integer values from 0 to 210-1 ie. The AD converter converts the analog voltage reading to the nearest equal value. These 0-5V values are divided into 1023 equal parts.

A Brief Note on the Voltage Sensor Module. That pin has 10-bit reading 210 1024. Since we will give a variable input voltage we need a regulated 5V volt for the Arduino and the Op-amp to operate. The Voltage Sensor is a simple module that can used with Arduino or any other microcontroller with input tolerance of 5V to measure external voltages that are greater than its maximum acceptable value ie.
A microcontroller cannot understand analog voltage directly.
This should be above 62V since the dropout voltage is 12V and preferably between 9V and 12V. This regulated voltage will be provided by the 7805 Voltage regulator. Neutral PH7 set to 0V this means that the voltage will go into the minuses when reading acidic PH values and obviously cannot be read by the analog Arduino port. 82V is beyond maximum of Arduino pin voltage which is 5V and it will fry that pin if plugged directly. ADCs convert analog inputs that can vary from zero volts on up to a maximum voltage level that is called the reference voltage. That is why we have to use an Analog to Digital Converter or ADC in shortAtmega328 which is the brain of the Arduino Uno has 6 channel marked as A0 to A5 10-bit ADC.
