Description: This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, for Arduino analog 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 analog module is 0.00489V (5V / 1023), so the voltage detection module detects a minimum input voltage of 0.00489V × 5 = 0.02445V. Specification: Voltage input range: DC0-25V Voltage detection range: DC0.02445V-25V Voltage Analog Resolution: 0.00489V DC input connector: Terminal cathode connected to VCC, GND negative pole Output interface: + 5V or 3.3V – GND S for Arduino AD pinsPackage included: 5* Voltage Sensors
