The Voltage Divider can detect the supply voltage upto 80V. The Voltage Divider module is based on resistor(1K and 15K Precision resistors) divider principle. The voltage detection module allows the input voltage to reduce 16 times. As the Arduino analog input voltage is up to 5V, so voltage detection module's input voltage can not be greater than the 5Vx16 = 80V. Because of the Arduino's 10 bit ADC, that means sampling resolution are 0.00489V(5V/1023).So the module's minimum input voltage is 0.00489Vx5=0.02445V.
