单片机与GSM模块通信C51程序（温度采集与短信控制）

单片机与控制TC35I

1）单片机检测温度，显示温度（保留1位小数），将温度值编辑成短信息发送给手机；

2）手机发送短信息给单片机，控制单片机继电器动作：如，发送open1，继电器1打开，

发送close1，继电器1关闭，发送open2，继电器2打开，发送close2，继电器2关闭-C51 microcontroller and GSM module communication procedures (temperature acquisition and SMS control)

MCU and control TC35I

　　1) microcontroller detects temperature display temperature (keep a decimal), the temperature value edited into short messages to mobile phones

　　2) mobile phones to send text messages to the microcontroller, microcontroller relay control: such as sending open1, relays an open,

　　　 Send close1, relay 1 off, sending open2, relay 2 opens, sends close2, Relay 2 closes.
