Arduino Smart Home

Arduino & Raspberry pi "IOT Smart-home" project, based on the Arduino MKR family.

The main java application is a Java 17 Spring Boot application that runs on a Raspberry 4 8gb connected to my home-network. The application provides a REST api for the IOT-devices to routinely post new readings to, and to get readings from. All readings are recorded into a local PostgreSQL 13 database running on the Raspberry pi.

Per now the logged data is not used for much, except for some machine learning side-projects. However, the goal will eventually be for there to be a web portal/GUI where information from the system can be neatly displayed and retrieved, in addition to being able to manage the system and individual devices.

Device list

• Raspberry Pi 4 running Java 17 and PostgreSQL 13
• Arduino MKR 1000 WiFi running two ds18b20 temperature sensors (Indoor/Outdoor)
• Arduino MKR 1010 WiFi running a MKR ENV Shield Rev 2 (Indoor)

Progress

• Indoor/Outdoor thermometers
• Temperature Database
• Indoor environmental reader
• Environmental Database
• REST API
• Cool web portal
• Display cool statistics
• More devices/sensors / update DB and API accordingly
• Update arduino software to be "smarter" (react to different http responses and act accordingly, offline storage, etc...)

Temperature Reading example

{
    "ID": 241,
    "TIME_STAMP": "Aug 4, 2022, 5:31:44 PM",
    "INDOORTEMP": 24.25,
    "OUTDOORTEMP": 19.06
}

Environmental Reading example

{
    "ID": 11,
    "TIMESTAMP": "Jan 14, 2023, 1:42:52 PM",
    "TEMPERATURE": 24.87,
    "HUMIDITY": 34.01,
    "PRESSURE": 99.03,
    "LUX": 15.48,
    "UVA": 0.0,
    "UVB": 0.0,
    "UVI": 0.0
}

note: Beware that all UV data is 0 since this reader is indoors
