DFRobot Gravity Analog Voltage Divider V2 The voltage detection module based on the principle of resistor voltage pision can detect the voltage and power level with the Arduino sensor expansion board, and can monitor the power of interactive media works or the power supply of robots. The voltage detection module can reduce the input voltage by 5 times. Since the maximum analog input voltage of Arduino is 5V, the input voltage of the voltage detection module cannot be greater than 5Vx5=25V. The minimum analog resolution of Arduino is 0.0049V, so the minimum input voltage of the voltage detection module is 0.0049Vx5=0.0245V.
