Description: 本文提出的多功能数字温度计系统设计, 采用了AT 89S52 单片机、DS18B20 单总线数字温度传感器、DS1302
时钟日历芯片、ISD1420 语音录放芯片等器件。该数字温度计的测量范围为0~ 120 e , 可实现多点测控。显示分辨
率为0. 1 e , 误差[ ? 0. 5 e 。交替显示实时日期、时间、温度 通过按键设置日期、时间、报警温度的上限和下限值。
当温度超过设定的上限或下限时, 能发出声、光报警提示。能实现实时语音播报日期、时间、温度等。该系统具有测量
精度高、工作稳定、功能多、使用方便等特点, 可以广泛应用于工农业生产、人们日常生活中, 对温度进行测量与监控,
具有较好的实用价值。-This paper presents the design of multifunction digital thermometer system, AT 89S52 MCU DS18B20 single-bus digital temperature sensor, DS1302 clock calendar chip, ISD1420 voice recorder chip devices. The digital thermometer measurement range of 0 ~ 120 e, and multi-point measurement and control. The display resolution is 0. 1 e, error [? 0 5 e. Alternately display real-time date, time, and temperature button to set the date, time, alarm temperature upper limit and the lower limit. When the temperature exceeds the set upper or lower limit, and audible alarm. To achieve real-time voice broadcast date, time, and temperature. The system has high accuracy, stable, multi-function, easy-to-use features, can be widely used in industrial and agricultural production and people' s daily life, temperature measurement and monitoring, has good practical value.
