Description

Description:

  • Size: 25mm×13mm/0.98″×0.51″(approx)
  • This module is based on principle of resistive voltage divider design,
  • can make the red terminal connector input voltage to 5 times smaller. input voltages up to 5v,
  • the voltage detection module input voltage not greater than 5Vx5=25V
  • (if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V)
  •  AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023),
  • so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.
  • Voltage input range : DC0-25 V
  • Voltage detection range : DC0.02445 V-25 V
  • Voltage analog resolution : 0.00489 V
  • Output Interface : “+ ” connected 5/3.3V, “-” connected GND, “s” connected AD pins
  • DC input interface : red terminal positive with VCC, negative with GND
  • By 3P connector, connect this module with the expansion of board,
  • not only makes it easier for you to detect voltage battery,
  • can also use the IICLCD1602 LCD to display voltage.
