摘　　要：在分析数字温度传感器DS1722的功能、特点、应用领域以及时序的基础上,设计了由传感器DS1722和单片机89C51构成的温度测量系统。实验证明:数字温度传感器DS1722在0℃～100℃测温范围内误差小于±0.5℃,且最远传输距离为5m。The function、characteristics、applications and timing of digital thermometer DS1722 are analyzed. Based on these, we had designed the temperature measuring system,which is made up of the digital thermometer DS1722 and singlechip。Through experiment,it proves that the digital thermometer DS1722 has error less than ±0.5℃ in 0℃～100℃,and its farthest transmission distance is five meters
