0-25V Arduino Voltage Sensor Module

This module helps you to measure external voltage using a microcontroller like arduino.

This sensor is made using a voltage divider circuit. Also, this voltage divider circuit includes two resistors of 30kohm and 7.5kohm. When a potential is applied to this circuit, we can get the voltage difference in the voltage divider point via the signal pin.

 It is capable of reducing five times of the voltage of the input terminal connection. You can use a maximum voltage of 5V on the ADC side of the module so that it allows a maximum of 25V on the input side. 

For 3.3V Systems, this module is only capable of  measuring voltage upto 16.5V,
3.3V * 5 = 16.5V
