ABSTRACT
The polyurethane materials have been widely used in the field of antibacterial, medical, waterproof and moisture permeable. Therefore, this paper mainly studies on the determination of the film formation rate of polyurethane, and designs a film formation rate measuring instrument based on the Atmega328P single chip microcomputer and BH1750 light intensity measurement chip. This design compares the advantages and disadvantages of the currently widely used film formation rate measuring instrument and improves its multiple sensors into a high-precision main sensor. Measurement requirements are reduced, and the size of the instrument is also reduced, making it easier and more portable. Moreover, it can be used not only to measure the film formation rate of polyurethane, but also to determine the film formation rate of other materials.
