Voltage Detection Module Sensor Electronic Bricks

Product information:
This module is designed based on the resistance voltage division principle, which can reduce the input voltage of the terminal interface by 5 times, and the voltage of Arduino analog input is 5V, then the input voltage of the voltage detection module cannot be greater than 5V × 5=25V (if 3.3V system is used, the input voltage cannot be greater than 3.3 vx5 = 16.5V). The analog resolution of this module is 0.00489V(5V/1023) because the AVR chip used in Arduino is 10-bit AD, therefore, the voltage detection module detects that the input small voltage is 0.00489V × 5=0.02445V.
