DC 0-25V Terminal Voltage Sensor Module
This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, for Arduino analogue input voltage up to 5V, then the input voltage of the voltage detection module can not be greater than 5V × 5 = 25V (if used 3.3V system, the input voltage can not exceed 3.3Vx5 = 16.5V).
Because for Arduino AVR chips used in 10 AD, so the resolution of the analogue module is 0.00489V (5V / 1023), so the voltage detection module detects a minimum input voltage of 0.00489V × 5 = 0.02445V.
