The program is designed to measure Termo teperatury and control heating and cooling network 1wire, consisting of temperature sensors DS18V20 (DS1820) and actuators (switches) DS2413. Control bus 1wire made via the serial COM port of the computer. To pair the COM port bus 1wire used a simple adapter independent production. The simplicity and low cost of network construction 1wire allows its use in everyday life, for the purposes of temperature monitoring and control of domestic heating and cooling systems.
