HomeSensors

Home Sensors based on Arduino

• All libraries can be downloaded using built-in arduino library manager or fetched from github

Architecture

• All nodes can comunicate with others using RFM69 wireless modules. Communiction is encrypted using AES.
• One master node with NodeID = 0 only listen to packets and send them through Serial to computer
• NodeID and NewtorkID can be set (and must be set) in EEPROM

Hardware:

All of them are cheap and can be bought easily on Ebay.
