PN结两端电压随温度变化，采用ADC0809采样的处理程序，送于LCD1602显示，采用18b20温度传感器的测温作为参考-PN junction voltage with temperature changes at both ends, using ADC0809 sample handling procedures, to send in the LCD1602 display, using 18b20 temperature sensor temperature as a referen

lcd+adc电压检测，含仿真和程序，已经调试通过啦-lcd1602+adc0809 that is good things！

数字温度传感器的驱动程序，可以从DS18B20中读取温度值，并且在LCD1602上显示出来-Digital temperature sensor driver, can read the temperature from DS18B20, and in LCD1602 displayed

利用AT89S52进行模拟到数字的采集，试用ADC0809，并通过LCD1602显示其采集的数字电压。-AT89S52 using analog to digital acquisition trial using ADC0809, LCD1602 display its acquisition of the digital voltage.
