| Abstract: | The paper has realized the rapid detection of heavy metals in food based on the photoelectric method and MSP430 control technology, which introduces the basic principle of photoelectric sensor detection and the light control circuit design in detail. According to the different wavelengths, light intensity is automatically adjusted to the best state and stable performance, which solves the traditional optical detection system＇ s performance drop in harsh environmental conditions. Experimental comparative analysis proves the accuracy and reliability of the system, which can shorten the test time to rapidly screen food samples on the field. |
