100pcs Standard Voltage Sensor Module for arduino Robot Smart Car

Module introduction: Based on the principle of resistance partial pressure, the module can reduce the input voltage of the terminal interface by 5 times, the maximum analog input voltage of Arduino is 5V, and the input voltage of the voltage detection module can not be greater than 5V x 5=25V (if the 3.3V system is used, the input voltage can not be greater than 3.3Vx5= 16.5V). Because the AVR chip used in Arduino is 10 bit AD, the analog resolution of this module is 0.00489V (5V/1023), so the minimum voltage of detection module of voltage detection module is 0.00489V x 5=0.02445V. Parameters: Voltage input range: DC - 2 - 25 V Voltage detection range: DC0.02445V-25V Voltage analog resolution: 0.00489V DC input interface: terminal positive electrode VCC, negative electrode GND Output interface: "+" connect to 5/3.3V, "-" connect GND, "s" connect to Arduino's AD pin.
