Design of Control Platform for Pineapple Pesticide Application Machine

In response to the waste and pollution issues during pineapple pesticide application, this article designs a pineapple pesticide application machine control platform based on STM32F103ZET6 microcontroller. The device utilizes Hall sensors and GPS modules to obtain speed data, and uses Kalman filtering fusion algorithm to fuse the data, reducing the maximum standard deviation of speed data from 0.433km/h to 0.173km/h. By constructing a PID algorithm and adjusting the output flow rate of the water pump, the error is controlled within 4%, ensuring that the spraying amount meets the standard and achieving precise spraying, reducing waste and pollution problems during pineapple spraying.
