Aiming at the nonlinear and coupling phenomena of temperature and humidity changes in the course of tea fixation, this paper proposes the FNN algorithm and its hardware implementation technology in the process of making tea. STM32F107 microcontroller is as the core of the whole system and the multi-point detection system is used in real-time collection of two parameters of temperature and humidity . In addition, data transmission is implemented between PC and I2C, SPI bus. FNN control is adopted to meet the process requirement of temperature and humidity change in process. The method improves the control precision of temperature and humidity and the quality of tea.
