Fit Robot Standard Voltage Sensor Module Components DIY Kit 2PCS US
Features:
This module is based on the principle of resistive voltage divider design;
can make the red terminal connector input voltage to 5 times.
Arduino analog input voltages up to 5 v,the voltage detection module input voltage not exceeds 5Vx5=25V.
(if using 3.3V systems, input voltage not exceeds 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 input voltage detection module is 0.00489Vx5=0.02445V.
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,
but also use the IICLCD1602 LCD to display voltage.
