USE OF THE 1-WIRE PROTOCOL IN SMART HOME COMPUTER SYSTEMS

The article examines the computer systems used in “Smart House”. A comparative analysis of these was carried out. It emphasized that such have a number advantages positive impact on human life and safety. use temperature measuring devices is widely to monitor Smart Home conditions. need install large sensors leads an increase complexity systems. Protocols for connecting microcontroller play important role system development. latest publications studies provides information widespread 1-Wire protocol various fields solve practical problems further improvement using this protocol. Two simulation models House” determining indoor based classic connection are presented. model standard uses: Arduino Uno board Atmega328p microcontroller, LM35 74HC4051D multiplexer. In protocol, following used: DS18B20 digital sensors. Information given operation which connect with interface, namely, there theoretical possibility addressing unlimited similar single-wire line. connected one output increased 12 order analyze demonstrate capabilities system. According results, parameters presented: possible connections, design, compact software code, frequency clock signal, cost results considered presented conclusions. Advantages disadvantages given.
