NEW Standard Voltage Sensor Module Test Electronic Bricks For Robot for Arduino

Size: 25mm×13mm/0.98″×0.51″(approx)

   This module is based on the principle of resistive voltage divider design,

   which can make the red terminal connector input voltage 5 times smaller. Arduino analog input voltages up to 5 v,

   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).

   Arduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023),

   so the minimum voltage of the 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 Arduino AD pins

   DC input interface: red terminal positive with VCC, negative with GND

   By 3P connector, connect this module with the expansion of board Arduino,

   not only makes it easier for you to detect voltage battery,

   can also use the IICLCD1602 LCD to display voltage.
