  • This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, A rduino 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 A rduino 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.


  • Voltage input range: DC0-25V

  • Voltage detection range: DC0.02445V-25V

  • Voltage analog resolution: 0.00489V


  • DC input connector:

  • The positive terminal connected to VCC,

  • The negative connected toGND

  • Output interface:

  • "+" is 5 / 3.3V,

  • "-" then GND,

  • "s" A rduino connected to the AD pin
