Description: 该电路由一片四双向模拟开关集成电路CD4066为核心构成。每个电路内部有四个独立的能控制数字或模拟信号传送的开关。当水箱无水时，由于180K电阻的作用，使四个开关的控制端为低电平，开关断开，LED 不发光。随着水位的增加, 由于水的导电特性，使得IC的13脚为高电平，S1接通，LED1点亮。当水位逐渐增加时，LED依次发光指示水位。水满时， LED4发光， 显示水满。同时T1导通， B发出报警声，提示水已满。不需要报警声时，断开开关K即可。 -The circuit consists of a four-way analog switch integrated circuit CD4066 core composition. Within each circuit to control four separate digital or analog signal transmission in the switch. When the tank water, the role of the 180K resistor, so that the four low-side switch control, switch off, LED does not light. As the water level increases, the electrical properties of water, making the IC' s 13 feet high, S1 connected to, LED1 lights up. When the water level gradually increased, LED turn light level indication. Is full of water, LED4 LED display full of water. At the same time conducting T1, B alarm will sound, indicating that the water is full. Do not need to sound the alarm when the disconnect switch K can be.

Description: ：提出了一种单总线上多个数字温度传感器DS18B20的自动识别方法。通过设计由译码器74LS138、二输入四
与非门74LSOOP、模拟开关CD4066组成的电路，同时应用Keil C51工具编写DS18B20数字温度传感器软件程序，在单片
机的控制下，系统以开机初始化形式获取并保存所有传感器的序列号，自动识别传感器并进行多点测温。实验结果表明，
系统能将获得的序列号与各传感器对应起来，使传感器可即装即用，实现了真正意义上的自动识别。-A method of the automatic identification of multiple DS18B20 digital thermometers on a 1一W ire bus has been offered
by designing a circuit composed of a 74LS138 decoder，two 74LS00P quad 2-input NAND gates and two CIM066 quad bilateral
switchs，and writing programs using Keil C51 for accessing these DS18B20s．Under the control of SCM ，the system reads and
stores all DS18B20s’ROM codes in the form of initialization after the system is powered on，and then identifies the thermometers
automatically and measures the muthi—point temperature．The experiment result shows a one—to—one correspondence between the
DS18B20s’ROM codes is read and the temperature measuring points，which enables the therm ometers’plug and play．So the sys—
tern realizes the automatic identification in the real sens
