摘要
温湿度偏高或者偏低, 都会使农业大棚中的农作物停止生长或者生长放慢, 因此将温湿度始终控制在适合农作物生长的范围内非常关键。所以, 现代化的农业大棚应该采用温湿度自动采集的监控方式, 从而调控农业大棚的温湿度, 以便适应大规模生产。整个系统由单片机及其外围电路以及无线发送模块两个部分组成: 单片机及其外围电路主要由MCU、温湿度传感器、人机交互组成, 通过温湿度传感器采集环境温度和湿度数据, 将采集的数据经由MCU进行处理, 再将数据流通过433 MHz无线模块发送给主机, 进而对机械设备进行控制。
Abstract
High or low temperature and humidity will stop or slow down the growth of crops in agricultural greenhouses. Therefore, it is crucial to keep temperature and humidity within the suitable range for crop growth. Automatic temperature and humidity collection monitoring mode should be adopted in the modern agricultural greenhouses to regulate the temperature and humidity of agricultural greenhouses, in order to adapt to large-scale production. The whole system consists of MCU and its peripheral circuit as well as wireless transmission module. The MCU and its peripheral circuit are mainly composed of MCU, temperature and humidity sensors and human-computer interaction. The temperature and humidity data are collected by temperature and humidity sensors and processed by MCU, and then are transmitted to the host through 433 MHz wireless module, so the machine equipment is controlled by the host.
