基于SIM900A的电池自动满电提醒及实时查询电量装置附单片机源码与仿真 -

/*******************************************************************************
* 标题: 基于SIM900A的自动充电提醒以及实时查询电量装置 *
* 时间 2018年10月10日16:12:42 *
* *
* 实验说明：本装置的核心是SIM900A模块，需要调用SIM900A指令。本原理图中ADC0832 *
的参考电压为5V,由7805稳压源提供7805的电源以及参考电压。检测电池的电压在9-15V之 *
间，采用分压方式，一个30K,一个10K电阻进行分压。假如检测电压为15V,则输入ADC0832 *
的电压为5V。依次类推。 *
*
********************************************************************************
* 实验心得：SIM900A是个难点，需要在电脑上进行调试。ADC0832进行AD转化的时候，需 *
要研究下时序图，在进行数据检测的时候需要进行两次检测，如果前后两次数据相等，那 *
么再返回得到的值，减少了测量误差。7805稳压源是个重要的部件，为了提供精确稳定的 *
5V参考电压 *
