Description: 呼吸监测GSM报警系统:通过热敏电阻电路采集相应的呼吸信号 然后使用硬件电路对相应的信号进行放大处理，再者进行数值比较得到相应的高低电平，再将此电平送入MSP430F149中，然后利用捕获程序计算两次呼吸之间的时间差，算出每分钟呼吸的次数。在12864液晶屏显示出来。当呼吸超出所设定的阈值时，单片机向SIM300手机模块发送要指令，并通过此模块向手机终端发送警报信息。-Respiration monitoring GSM alarm system: the corresponding respiratory signal collected by the thermistor circuit then use a hardware circuit to a signal corresponding to an enlargement processing Moreover numerical comparison to obtain the corresponding high and low, and then this level into the MSP430F149 The capture program, and then use the time difference between the two breathing calculation calculates the number of breaths per minute. 12864 LCD display. When breathing beyond the threshold set by the microcontroller to the SIM300 phone module Send To instructions, and send alarm information to the mobile terminal through this module. Platform: |
