## Components

- **WIZnet W5100 ethernet shield** x 1 ([docs](https://www.wiznet.hk/en/open-source-hardware/102-w5100s-ethernetshield.html?search_query=W5100+ethernet+shield&results=84))

## Article

Room thermostat on Arduino platform (Uno) with Ethernet shield Wiznet W5100. The implementation shows the operation of the thermostat in real operation. Used temperature sensor Dallas DS18B20 connected to OneWire bus with normal connection. Parasitic connections can also be used.
