-====== ​433 MHz RF Network ======+====== ​Wireless (RFNetwork ======
  
 I've been using a lot of WiFi modules but they are power hungry so powering them via battery for an extended period of time isn't really an option. To accommodate cheap battery powered sensors I want to build up a low power rf network and I've chosen 433 Mhz to do this. My plan is to build a small hub that will have the 433 transceiver along with a WiFi board that will convert rf signals to mqtt messages. This will allow me to produce various small battery powered circuits that I hope to tie into my home automation system. My starter project will be temperature sensors because they'​re easy, cheap, and will help with my [[projects:​wireless-boiler-zone-controller|wireless zone controller project]]. I also want a simple circuit that will automatically turn on the bathroom fan when the humidity gets too high (shower). I've been using a lot of WiFi modules but they are power hungry so powering them via battery for an extended period of time isn't really an option.
