摘要
针对恶劣工作环境下温度测量难的问题,提出了一种基于无线通信方式与一线数字式温度传感器的温度测量电路设计方案,设计出一款显示终端与温度测量探头分离的无线温度测量仪,避免测试人员置身于危险环境中测试温度。软硬件调试结果证明电路测量精度高、工作稳定可靠、无线传送距离可达100m。
A temperature measuring circuit based on radio frequency（RF） and 1-wire digital thermometer is designed and assembled.The display circuit and measuring circuit are separated,which can keep users out of dangerous environment during measuring the temperature.The software and hardware testing results show that the designed circuit is characterized by high accuracy,stable operation and a long transfer distance of 100 meters.
