The voltage detection module is based on the principle of the resistor divider. The measured voltage can be reduced so that the ADC pin for Arduino board can detect the voltage value after reduction, and the measured voltage can be calculated. Sampling resistor which is precision resistors, the precision of 0.5% and a temperature coefficient of 50PPM, in order to effectively ensure the detection accuracy.
