Devices work connected to a regular PC 
You can measure and record temperatures, solar radiation, flow, and much more with a regular PC and these unexpensive devices.
See online example of measurements
A Serial to 1-wire adaptor is used, along with one or more of these sensors. 
We highly recommend the use of the software LOGTEMP for Windows, a freeware program.  It displays graphics and values on screen, saves data as text file or MySQL database, transmits via ftp so you can publish the information on a web site, you can set alarms and configure it to send SMS or email, and so on.
Temperature monitoring is useful for Data centers, Solar water heating systems, Greenhouses, etc.
Specifications for the temperature sensors can be found here.
Solar radiation measurement is used for Solar water heating systems, for agriculture and other applications.
The pulse counter can be used for counting any event originated by a switch closure or a 0 - 5 volts voltage transition. As an example, water flow can be measured by means of having a flow meter with pulse output connected to this counter.
