Description
The Voltage Detection Module is a resistor divider-based board designed to measure higher DC voltages using microcontroller analog inputs. It scales the input voltage by a factor of 5, allowing safe measurement of up to 25V DC when used with a 5V ADC system. The module provides stable and predictable voltage scaling suitable for 10-bit ADC resolution such as Arduino AVR boards. It ensures reliable signal conditioning while protecting the analog input from overvoltage. Ideal for battery monitoring, power supply measurement, and embedded voltage sensing applications.
