摘　　要：以AT89S52单片机为控制核心设计了数字温度报警器,以数字温度传感器DS18B20为检测元件,配合LED数码管来实现对环境温度的实时监测,温度超过预设范围时产生报警信号。本文对系统硬件电路以及软件进行了设计,并对系统进行仿真测试,结果表明温度报警器操作简单,功能实用,有一定的实用价值。A digital temperature alarm is designed with AT89S52 as the controling core and digital temperature sensor DS18B20 as the detecting element. The real-time monitoring is realized with LED digital tube. The alarm signal is generated when the temperature exceeds set range. In this paper, the system hardware circuit and software are designed and system simula- tion is tested. The result shows that the operation of the temperature alarm is simple and the function is practical it has a certain practical value
