This design use of single-chip microcomputer as the control center, using the DS18B20 temperature sensor to monitor the temperature,using the the GSM module for remote real-time data and SMS alerts. This system has a good user interface, you can simply and easily modify the alarm value. This design uses the traditional design ideas that the hardware circuit first and the software program after. Hardware circuit include power supply circuit, a MCU system circuit, GSM module, TFT LCD circuit, serial communication circuit, independent key, buzzer circuit, EEPROM circuits. Software program that includes the main program, GSM communication programs, computer programs, keystroke scanners, TFT LCD program. Organic combination of hardware and software, implements a complete remote temperature measurement system. This design allows for real-time monitoring of SMS alarm temperature, ambient temperature can also be sent to the server in real time and to analyze your data on the computer as a whole. Remote temperature monitoring system based on GSM module has good human-computer interaction, low cost, high reliability, widely used in practice.
