Abstract: A snowflake beef information tracing system based on wireless sensor networks was developed to trace and
collect information on snowflake beef effectively. In the system, nodes composed of STM32 chip, CC1101 radio frequency
module and SHT10 sensor module were used to collect temperature and humidity data. The system collected information
about snowflake beef grading with a charge-coupled device (CCD) camera and sent the data to the server for storage. The
system connected different data tables with the designed traceability code to achieve remote tracing of the information on
snowflake beef on the web. Results showed that, in low temperature and high humidity environment, the temperature error of
the system was less than ± 0.3 ℃ and the humility error was less than ± 1.0%. It took about 6 seconds to photos of beef and
the accuracy of tracing beef information on the web platform was 100%. The system could work steadily to implement each
function normally.

Key words: snowflake beef, wireless sensor networks, information traceability, two-dimensional barcode
