Description: This module is based on principle of resistive voltage divider design Make the red terminal connector input voltage to 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), 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 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, Makes it easier for you to detect voltage battery Material: Plastic Size: 2.6*1.4cm Package include: 1x Standard Voltage Sensor Module
