摘 要
目前，随着我国经济的快速发展和国民生活质量的提高，人们在吃饱的基础上 开始追求吃好和食品绿色安全，因此解决这一问题的植物生长环境监测行业发展也越发迅速起来。当前相关设备功能相对单一，控制系统较为简单，智能化程度有限，不适用于大规模实验，而且成本高，数据传输采集能力不足，不能很好地满足研究需要。在这个问题的基础上，此次设计采用STM32单片机作为主控芯片，结合植物生长环境中影响因素较大的参数，如植物生长环境的温湿度，植物生长环境中的光照强度和植物当前生长环境中的大气压，用户可以根据需求进行这些参数上下限值的设置，当监测到当前监测的参数不在设置的范围之内进行声光报警提醒管理人员，及时对其进行处理，该设计可以满足当前植物生长环境监测的需求，为植物工厂研究的进一步深入提供了保证。

Abstract
At present, with the rapid development of our economy and the improvement of the quality of life, people began to pursue good eating and food green safety on the basis of satiety. Therefore, the development of plant growth environment monitoring industry to solve this problem has become more and more rapid. At present, the function of relevant equipment is relatively simple, the control system is relatively simple, the degree of intelligence is limited, is not suitable for large-scale experiments, and the cost is high, the data transmission and acquisition ability is insufficient, can not well meet the needs of research. On the basis of this problem, the design uses STM32 microcontroller as the main control chip, combined with the plant growth environment in the influence factors of larger parameters, such as the temperature and humidity of the plant growth environment, the intensity of light in the plant growth environment and the atmospheric pressure in the plant growth environment, users can set the upper and lower limits of these parameters according to the needs, When monitoring the current monitoring parameters are not set within the scope of sound and light alarm to remind the management staff, timely processing, the design can meet the needs of the current plant growth environment monitoring, for plant factory research further provides a guarantee.
Key words：plant growth; Temperature and humidity; Light intensity; Atmospheric pressure; Sound and light alarm
