Abstract: A water quality monitoring device and a monitoring method thereof are provided. The water quality monitoring device includes a water tank, a first and a second optical detection devices and a control circuit. The water tank has an accommodating space to carry a liquid. The first optical detection device provides a first light to detect and obtain a first reference light intensity, a first scattered light intensity, and a first penetrating light intensity. The second optical detection device provides a second light to detect and obtain a second reference light intensity, a second scattered light intensity, and a second penetrating light intensity. The control circuit calculates a water quality detection value of the liquid based on the first reference light intensity, the first scattered light intensity, the first penetrating light intensity, the second reference light intensity, the second scattered light intensity, and the second penetrating light intensity.
