基于传感器的单片机植物环境监控系统

Monitoring system of plant environment based on the single-chip computer and sensor

本设计采用新型单总线数字温湿度传感器DHT11和光强度传感器BH1750,以STC89C52单片机为控制器,LCD1602为显示模块,蜂鸣器为报警模块,用按键对最适宜温湿度、光照进行设定,对植物生长的室内温度,湿度,光照进行测量。其中最适宜温湿度、光照都可以根据不同季节进行人为设置,当测量值超过设定值时,报警装置即会启动。对搭建后的系统测试结果表明:整个系统结构简单,功耗低,硬件接口少,易于嵌入其他系统中,经济实用。

This design uses new single-bus digital temperature and humidity sensor DHT11 and light intensity sensor BH1750, Based on STC89C52 controller, taking LCDI602 as the display module, as with buzzer alarm module, and using the button setting the most suitable temperature , humidity and light, completion of the measurement of plant growth room temperature, humidity, light.Among them the most suitable temperature, humidity and light intensity can be artificially set depending on the season, when the measured value exceeds the set value, alarm will be activated.The test results of the system set up show that： the whole system has simple structure, low power consumption, less hardware interface, it is easy to be embedded in other systems, and economical and practical.
