基于单片机的蔬菜大棚的监控系统设计 摘要 在当今社会快速发展和科技发达的背景下，采用智能设备来提高日常作业和农业生产已经成为一种常态，温室是目前较为常见的一种农业生产方式，可实现反季节的农作物供应，已然成为当前反季节蔬果供应的重要生产基地。如何在有限的资源下尽可能的提高农作物产量，对于温湿度的监测是至关重要的。 基于此，本文提出了一种基于51单片机的智能大棚系统，方案采用51单片机作为系统的主控芯片，通过SHT30温湿度传感器来模拟实现对温室内部的温湿度信息进行检测，为了让系统更加智能，系统可通过按键对温湿度的阈值进行设置，当系统检测到温湿度数据不在阈值范围内时启动声光报警，为了提高植物光合作用，通过光敏电阻进行光线检测，并在光线过低时自动开启补光灯。通过OLED显示器可以实时观察系统实时检测到的各类数据。 通过软硬件设计对方案进行实现，然后对设计出的硬件系统进行功能测试，分别对系统各模块功能进行测试，从测试结果可以看出，本文所设计的基于单片机的智能大棚系统符合设计要求，在满足设计的同时，还具有成本低廉、功能齐全、结构简单等优点，具有较好的社会实际使用价值。 关键词：温室大棚；温湿度监测；光线强度检测；51单片机 Abstract In the context of rapid social development and advanced science and technology, it has become normal to use intelligent equipment to improve daily operations and agricultural production. Greenhouse is a relatively common agricultural production mode at present, which can realize the supply of off-season crops and has become an important production base for the supply of off-season vegetables and fruits. How to improve crop yield as much as possible with limited resources is very important for temperature and humidity monitoring. Based on this, this paper puts forward a kind of intelligent greenhouse based on 51 single chip microcomputer system, the scheme adopts 51 single chip microcomputer as main control chip of system, through SHT30 to simulate the implementation of the greenhouse temperature and humidity sensor for detecting the internal temperature and humidity information, in order to make the system more intelligent, the system can be set up by the key threshold value of temperature and humidity, When the system detects that the temperature and humidity data is not within the threshold range, it starts the acousto-optic alarm. In order to improve the photosynthesis of plants, it detects the light through the photosensitive resistor and automatically turns on the light supplement lamp when the light is too low. The OLED display allows real-time observation of all kinds of data detected by the system. By hardware and software design scheme for im
