Abstract

This paper presents a design of temperature collection and warning system based on GSM, which is mainly based on the LM3S811 micro controller. DS18B20 temperature sensor collects temperature values in real- time,and the intrared keyboard and LCD12864 make a simple menu. When the temperature value collected by the DS18B20 is greater than the upper limit or less than the lower limit set before,the system will show the alarm information by the LCD12864 and send the current temperature value information to mobile phone which numbers was set by the infrared keyboard with the sound and light alarming. Through the hardware platform testing,the results show that the system is stable and reliable.
