3pcs DC 0-25V Voltage Tester Terminal Sensor Kit 

   

Size: 25mm×13mm/0.98"×0.51"(approx)

   

TThis module is based on principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller.For 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). For Arduino 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 For 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 For Arduino, not only makes it easier for you to detect voltage battery, can also use the IICLCD1602 LCD to display voltage.
