Original author: rena (source: https://1technophile.blogspot.com/2016/04/433tomqttto433-bidirectional-gateway.html)

## 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))
- **Arduino UNO** x 1 ([docs](https://www.farnell.com/datasheets/1682209.pdf))
- **433Mhz Receiver XD RF 5V and transmitter FS1000A** x 1

## Article

It enables to:

- receive MQTT data from a topic and send RF 433Mhz signal corresponding to the received MQTT data

- publish MQTT data to a different topic related to received 433Mhz signal

Materials:

- Arduino UNO

- W5100 Ethernet shield

- 433Mhz Receiver XD RF 5V and transmitter FS1000A
