DS18B20温度控制器是以美国MAXIM/DALLAS半导体公司的单总线温度传感器DS18B20为核心，以ATMEL公司的AT89C52为控制器制作的结构简单、测温准确、具有一定控制功能的智能温度控制器。适合于恶劣环境的现场温度测量，如：环境控制、设备或过程控制、测温类消费电子产品。现实生活中的电冰箱，电脑机箱，就使用的这种经济的温度传感器显示工作环境温度。通过这种动态的温度测量，能实时的了解各种仪器设备的工作温度，进而判断仪器设备工作是否正常。-DS18B20 temperature controller is based on the United States MAXIM/DALLAS Semiconductor single-bus temperature sensor DS18B20 as the core, ATMEL Corporation AT89C52 produced for the controller structure is simple, accurate temperature measurement has a certain control functions of the smart temperature controller. Suited to harsh environment of the scene temperature measurement, such as: environmental control, equipment or process control, temperature measurement Consumer electronic products. Real-life refrigerators, computer chassis, on the use of such economic temperature sensor shows the temperature working environment. Through this dynamic temperature measurement, real-time understanding of a variety of instruments and equipment operating temperature, and the

遥控数字钟应用程序，应用于多种数字钟接口，可以遥控设备，省力。自制LED电子钟在很多电子报刊杂志上都可以见到，但大多数在断电后都要重新设置时间等 参数，给使用带来很多不便。也有用后备电池作为备用电源的，但往往体积较大。本文介绍 的LED电子钟克服了以往的弊端，而且采用了家电通用的红外遥控器进行控制，方便使用。 有一路闹铃输出，可以通过遥控器设置闹铃时间及允许与否。-digital clock remote control applications, digital clock used in a variety of interface, remote-control equipment, effort. Homemade LED electronic bell in many electronic newspapers and magazines can all, but most of the power outages after the re setup time and other parameters to use in many ways. Also useful as a standby battery backup power, but often larger. This paper introduces the LED electronic clock to overcome the shortcomings of the past, and the use of common household appliances infrared remote control, and ease of use. A way Alarms output, the remote control can set the alarm time and allow it or not.
