113、程序
说明： 113、基于51单片机老人生理智能监控GSM短信
本设计由STC89C52单片机电路+火焰传感器电路+加速度传感器+心率传感器电路+SIM800A_GSM模块电路+电源电路组成。
该系统实时监测老人是否跌倒，是否周围有火以及心率情况。
1、如果火焰传感器检测到火焰，则GSM向特定手机发送：Fire！
2、如果ADXL345检测到老人跌倒了，则GSM向特定手机发送：Fall！
3、如果心率传感器检测到老人心率高于120，则GSM向特定手机发送：High Heart！
4、注意本设计一次上电上述情况每个只能触发一次上报短信，不会连续发送，防止反复发送，请放心使用。
5、短信处理过程有GSM信号灯指示。
6、GSM模块是SIM800A，该模块和SIM900A电路程序完全兼容外观外形一模一样。(GSM SMS for elderly physiological intelligent monitoring based on 51 MCU
This design consists of STC89C52 MCU circuit + flame sensor circuit + acceleration sensor + heart rate sensor circuit + sim800a_ GSM module circuit + power supply circuit.
The system monitors whether the elderly fall down, whether there is fire around and heart rate in real time.
1. If the flame sensor detects a flame, the GSM sends: fire!
2. If adxl345 detects that an old man has fallen, the GSM sends a specific mobile phone: fall!
3. If the heart rate sensor detects that the heart rate of the elderly is higher than 120, the GSM sends a message to a specific mobile phone: high heart!
4. Pay attention to the design of a power on, each of the above conditions can only trigger a report SMS, will not be sent continuously, to prevent repeated sending, please rest assured to use.
5. SMS processing process is indicated by GSM signal light.)

缺水报警器
硬件
1.主控板上有2个LED灯白色插座，连接2个LED插头
2.主控板上有一个缺水报警探头插座，连接缺水测试探头
3.主控板上有一个蜂鸣器
功能
1.上电后蜂鸣器鸣叫一声，进入工作状态
2.进入工作状态后，利用探头进行自动测试，若发现没有达到一定的水量（检测端口断开），便立刻进入报警状态，红LED闪（蓝灯灭），蜂鸣器鸣叫，LED灯和蜂鸣器的鸣叫频率均为2HZ。（蜂鸣器为4khz的压电式蜂鸣器）
3.或者将探头短接，也将视为有水，则蓝灯长亮（红灯灭，蜂鸣器不叫）。
(Water alarm hardware 1 master board has two LED lights white socket, connect two LED plug 2. The main control board has a water alarm probe socket, connect the test probe is water 3 main control panel a buzzer function 1 after power buzzer sound, into the working condition (2) to enter the work state, the use of automatic test probe, if it did not reach a certain amount of water (test port off), they immediately go into alarm state, the red LED flashes (blue light), buzzer, LED lights and buzzer frequency chirping are 2HZ. (Buzzer piezoelectric buzzer for the 4khz) 3, or short the probe will also be seen as water, the long bright blue light (red light off, the buzzer is not called).)
