About HiLetgo 5pcs Voltage Detection Module DC 0~25V
Description: This module is based on principle of resistive voltage divider design, can 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), 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 Arduino AD pins. DC input interface: red terminal positive with VCC, negative with GND. Package included: 5* DC 0~25V Voltage Detection Module
