1.Description :
1 wire net thermometer system is adopt maxim company 's 1 wire' technology
which high-end networkmeasure temperature system . it is called TEMPer1W .
The system is a cheap miniLAN architecture ,it can be easily detected the
temperature of hundred points bythe computer . in addition ,DS18b20 digital
thermometer is 1 wire devices of  DALLAS maxim company produce,
which  have simple circuit, the characteristics of small size .So use it to form a temperature
measuring system, that will be a simple communication line, you can hang many of these
digital thermometer, very convenient.
2.Application Diagram:

if you not use 3.5mm audio splitter , one USB9097 only can connect two devices ;
if you need to connect many devices to computer ,you can follow the below picture .


when you plug the device into your computer one by one , the system will
automatically find the device unique ID, and the software display the ID.

 Installing instruction  (Note: Our software only support windows system .)
you need to install below drivers while you install the software at first time.
(1)USB Driver
a) install correspond system's driver , 32-bit systems with x32, 64-bit systems with x64 .
(2) 1 Wire Driver
a)install correspond system's driver , 32-bit systems with x32, 64-bit systems with x64 .
(3) Install the application: Double-click setup.exe of the root directory to install the software

Operating instruction
a)plug TEMPer18B20 into the computer and start to measure the temperature. See the picture below:
                  
This option allows you to settingtemperature of any channel  , for example: modify the calibration value, upper ,lower  and address of the alias, click "OK" button. If you connect a lot of measuring points, the software did not timely identify them, you can click "refresh device",measurement points have not been identified will be displayed in the software.
b) Loading the curve graph: You can load the curve graph on the "Curve" option part. Note, the device must be connecting to the computer to work, so the curve graph is the one about the real time temperature. And the function button can move, magnify, print, copy and save the curve graph. When you connect hundreds of test points, because the software interface is limited, can not be all of the test point curves show at the software . At this time, you can click on: "", select you want to show the test points

                              
c)Setting :In the "setting" option you can transfer the deferent measuring units,  the reading interval , the language and save  file settings .and set a upper and lower limit,

                                     
d)Alarm : in temperature alarm settings option , you can choose different alarm mode ;in "Email configuration" , you can send the temperature records to your mailbox. Before to do this, you must set the server of the mailbox, the mail address of sender and receiver, user's name and so on. And you also can set the sending conditions and interval in the option.

                                  
e) About Options: Display your current software version.
                             
if you don't want to use our software ,you also can use maxim One Wire Viewer software .
