Arduino-compatible voltage module can detect voltage up to 5v. Based on resistance points pressure principle, it can reduce the red terminals interface input voltage by 5 times, the max analog input voltage is 5V, then the input voltage module  is not more than 5V x 5 = 25V (if used 3.3 V systems, input voltage is not more than 3.3 Vx5 = 16.5 V). It used AVR microchip for 10 AD, so this module simulation resolution is 0.00489 V (5V / 1023), voltage module detect input voltage for minimum 0.00489 V x 5 = 0.02445 V.

        Connect it with sensor shield (Arduino-Compatible) by 3p cable, you can easily detect voltage, and monitor the electric quantity of interactive media works or robot battery power, make voltage monitor by IICLCD1602 LCD module display voltage.
