[SCM] temperature DL : 0: 此设计以单片机STC89C51为核心，由声音传感器采集脉搏信号，经过LM324前置放大电路、滤波电路和比较电路后得到与脉搏相关的脉冲信号，将该脉冲信号作为定时/计数器T1中断信号交由单片机进行脉冲周期的计算，T0做定时器。然后得出每分钟的脉搏搏动次数(即心率)，并将结果1602LCD上显示心率。在对人体脉搏检测时，具有检错排错的功能。若出现误操作（如不小心移动时产生的噪声）造成检测到的心跳次数不正确的结果，所以在程序中检测时间到达第5秒时，先对其进行计算，若结果超出正常范围则自动返回重新检测，直至结果正确，再继续检测5秒，最终由单片机计算出结果。在测量数据超过正常范围(如大于120次／min或小于45次／min)时自动重新开始检测。-Single-chip STC89C51 this design as the core, by the sound pulse sensor signal acquisition, the LM324 preamp circuit, filter circuit and compare the circuit to be associated with the pulse of the pulse signal, the pulse signal as the timer/counter interrupt signal cross-T1 single-chip pulse by calculating the cycle, T0 timer so.And then concludes that the pulse per minute pulse frequency (ie heart rate), and the results show 1602LCD heart rate.

[SCM] chashengboceju DL : 0: AT89S52单片机控制的超声波测距，主程序首先对系统环境初始化，设置定时器T0工作模式为16位的定时计数器模式，置位总中断允许位EA并给显示端口P0和P2清0。然后调用超声波发生子程序送出一个超声波脉冲，为避免超声波从发射器直接传送到接收器引起的直接波触发，需延迟0.1ms(这也就是测距器会有一个最小可测距离的原因)后，才打开外中断0接收返回的超声波信号。由于采用12MHz的晶振，机器周期为1us,当主程序检测到接收成功的标志位后，将计数器T0中的数（即超声波来回所用的时间）按下式计算即可测得被测物体与测距仪之间的距离,设计时取20℃时的声速为344 m/s则有： d=(C*T0)/2 =172T0/10000cm（其中T0为计数器T0的计数值）测出距离后结果将以十进制BCD码方式LED,然后再发超声波脉冲重复测量过程-AT89S52 MCU-controlled ultrasonic ranging, the main program first initializes the system environment, set the timer T0 mode for 16-bit timer counter mode, the set EA and the total Interrupt Enable bit ports P0 and P2 to show clear 0.
