This module is designed based on the principle of resistor divider, which can reduce the voltage of the terminal interface input by 5 times. The Arduino analog input voltage is up to 5V. The input voltage of the voltage detection module cannot exceed 5V×5=25V (if 3.3V is used) System, input voltage can not be greater than 3.3Vx5=16.5V). Because the AVR chip used by Arduino is 10-bit AD, the analog resolution of this module is 0.00489V (5V/1023), so the minimum voltage detected by the voltage detection module is 0.00489V×5=0.02445V.
Voltage input range: DC0-25V
Voltage detection range: DC0.02445V-25V
Voltage analog resolution: 0.00489V
DC input interface: Connect positive terminal to VCC and negative terminal to GND
Output interface: "+" is connected to 5/3.3V, "-" is connected to GND, and "s" is connected to the AD pin of Arduino
