Smart Electronics DC 0-25V szabványos feszültségérzékelő modul teszt Electronic Bricks Smart Robot barkácsoláshoz
Smart Electronics DC 0-25V Standard Voltage Sensor Module Test Electronic Bricks Smart Robot for Diy
Description:
Quantity:1pc
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.
