This voltage sensor module is based on resistive voltage divider design principles. It is capable of reducing five times 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. If 3.3V is used, the input voltage must not exceed 16.5V.
Due to AVR chips using 10-bit ADC, the maximum resolution of this module is 0.00489V (5V / 1023), so the voltage detection module detects minimum input voltage is 0.00489V × 5 = 0.02445V.
