1、完整版宠物定时喂食器设计中英文翻译The digital temperature sensor of DS18B20The digital temperature sensor of DS18B20, This product uses the American DALLAS companys DS18B20 network digital temperature sensor chip package. but become wear-resistant touch, the physical volume is small, convenient, packaging form is va

2、ried , Suitable for all kinds of narrow space in digital temperature test and control field equipment. Unique 1-WireTM interface requires only one port pin for communication. Multidrop capability simplifies distributed temperature sensing applications, requires no external components, Can be powered

3、 from data line. Power supply range is 3.0V to 5.5V, Zero standby power required, Measures temperatures from -55C to+125C. Fahrenheit equivalent is -67F to+257F, 0.5C accuracy from -10C to +85C, Thermometer resolution is programmable from 9 to 12 bits, Converts 12-bit temperature to digital word in7

4、50 ms (max.).User-definable, nonvolatile temperature alarm settings, Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition).Applications include thermostatic controls, industrial systems, consumer products, thermometers,

5、or any thermally sensitive system.1、the description of technique function:1)Single-line interface is unique, DS18B20 while linking with microprocessor only need a line can immediately carry out the double of microprocessor and DS18B20 toward the communication.2)measure scope-55 +125 , proper measure

6、 resolutions 0.5 .3)support several set nets function, several DS18B20 can merge at unique three on-line, the most can merge 8, if amount was excessive, it would make power supply the power electric voltage over low, result in thus the signal delivers of unsteady, the realizations order to measure m

12、a distribute type the temperature spread the feeling application didnt need an external component to use data total line power supply, the electric voltage scope has never needed to provide for use the power diagraph temperature scope for the 3.0-5.5 Vs BE-55 to+125 .The Fahrenheit is equal hence-67

13、-257 Fahrenheit degree-10 go to+85 accuracy inside the scope is 0.5 The temperature spreads a feeling machines programmable resolution to convert into 12 number formats for 912 temperatures biggest be worth to 750 a milli- of second the customer can define of not and easily lose sex temperature to r

14、eport to the police to establish an application to include a constant temperature control, industrial system, consume electronics product thermometer, or any hot sensitive systemThe number thermometer that describes the DS18B20 provides 9-12(the programmable equipments temperature read a number. The

15、 information is disheveled hair to send to connect through a line from the DS18B20, so central microprocessor and DS18B20 only have a per line conjunction. For read and write and the temperature conversion can acquire energy from the data line, dont need to circumscribe the power. Because each DS18B

16、20 includes a special ordinal number, several ds 18 bs 20 seses can be existed to a total line at the same time. This makes the temperature spread a feeling machine to place in many different places. Its use is a lot of, include an air condition environment control, detect equipments inside the building or machine, and carry on process monitor and control.
