摘要
本文设计了一个太阳能自供电温湿度监测系统,利用太阳能电池板吸收太阳能,并通过CN3791调控使太阳能电池始终以最大功率点供能,同时在太阳能光照充足的情况下,让太阳能电池给锂电池充电,这样在太阳能光照强度不足的情况下利用锂电池维持系统的正常运行。以ESP8266为核心控制芯片,利用GPRS节点连接到互联网上,传输温湿度模块测量的数据,并利用MQTT将数据传输到物联网平台上,实现后台实时监测,这样不需要连接到WiFi也可以实时观测温湿度数据。
In the paper,a temperature and humidity monitoring system is designed that self-powered by solar energy.It uses solar cells to absorb solar energy,and the solar cells can provide the maximum power through the CN3791 regulation.Moreover,the solar cells can charge the lithium ion batteries while it has sufficient solar illumination,and lithium ion battery can maintain the operation of the system while it has insufficient solar illumination.The system use ESP8266 as the core control chip,and GPRS node to connect to the Internet and transmit the measured temperature and humidity data.Lastly,the system use MQTT to release data on a Internet of things platform,thus realizing the real-time data monitoring without WiFi connection.
