基于单片机的智能蓝牙灌溉系统

Intelligent Bluetooth Irrigation System Based on Single Chip Microcomputer

本文介绍了由STC89C52单片机为核心,能够满足现代农业需求并且成本较低的智能蓝牙灌溉系统。本系统可有手动模式与智能模式,通过手动模式可强制开关继电器水泵。在智能模式中,当检测到的土壤湿度值达到设定的临界值时,蜂鸣器工作触发报警,LED灯闪烁并通过蓝牙串口模块发送至手机APP,同时水泵开启,从而实现自动灌溉。本系统造价低,功能齐全适合大规模推广。

This paper introduces the intelligent Bluetooth irrigation system with STC89C52 microcontroller as the core,which can meet the needs of modern agriculture and has low cost.The system can have manual mode and intelligent mode,through the manual mode can be forced switch relay pump.In the intelligent mode,when the detected soil moisture value reaches the set critical value,the buzzer will trigger the alarm,the LED light will fl ash and be sent to the mobile APP through the Bluetooth serial port module,and the water pump will be turned on at the same time,so as to realize automatic irrigation.The system has low cost and complete functions,which are suitable for large-scale promotion.
