Aiming at the problems of poor real-time performance, weak local interaction and limited data processing capacity of traditional agricultural monitoring systems, this paper presents an intelligent farm monitoring and control system based on ESP32-P4 and a 7-inch IPS touch screen. Taking the dual-core RISC-V ESP32-P4 with a main frequency of 400 MHz as the main controller, the system drives the display screen via the MIPI-DSI interface and adopts the LVGL graphics library to realize a high-frame-rate local human-machine interaction interface. It integrates five types of sensors for temperature, humidity, soil moisture, light intensity and carbon dioxide concentration, and supports Wi-Fi cloud data transmission as well as closed-loop control functions including automatic irrigation and environmental regulation. The test results show that the interface refresh rate is no less than 28 FPS, and the control response time is less than 100 ms. The system can satisfy the requirements of real-time monitoring and precise control for small and medium-sized intelligent farms.References
