Abstract Based on the principle of transmission turbidimetry, a simple turbidimeter was designed based on students' experience and easy to be made by students. The data of incident light and transmitted light were obtained by using the light intensity sensor built in smart phone, and the turbidity of the sample could be quantitatively measured by using the standard curve drawn with standard solution. The self-made turbidimeter could be applied to a variety of exploratory experiments and scientific practice activities, which was not only a practical experimental tool, but also a process of deep learning for students.
