Smart Sleep Alarm

An alarm designed to monitor the enviroment of the bedroom such as light intensity, temperature, noise level, air quality, which is then displayed on a web interface hosted on the RPI.

This web interface will show both latest values and a history of recorded values along with tips on how to improve your sleep enviroment. As well as having the ability to set alarms and control the RGB on the device.

For the sound to work you'll have to connect a speaker to the RPI with an AUX cable

- Raspberry Pi 4 Model B
- 16x2 LCD Display

- Sparkfun Sound detector
- DS18B20 One-wire Temperature Sensor
- FlyingFish MQ gas sensor
- LDR light sensor

- MCP3008 ADC
- 5V to 3.3V Logic level converter

For more detail, see one of the following files:

I strongly recommend you create a new separate user for this, which you can easily do with

sudo adduser smartalarm

You also might want to give the user administrative rights

sudo usermod -aG sudo smartalarm

You can get the code for the device, API, and web interface from the Github Repository
Be sure to clone this repo into the home directory of the newly created 'smartalarm' user!

To set up the web server you'll need to have Apache installed, which you can do with the following command:

sudo apt install apache2 

After you've installed apache you'll need to make some configurations

sudo nano /etc/apache2/sites-available/000-default.conf

and after DocumentRoot change the

/var/www/html

to

/home/smartalarm/smart-sleep-smartalarm/Frontend

where is your user's name

It's important to first start the API before you start the Device, as it'll need to gather data from the database through the API.

You can easily start the API by running the following:

python3 -u /home/smartalarm/smart-sleep-smartalarm/Backend/api/app.py

After the API successfully started you can start the device

You can start the device by running the following:

python3 -u /home/smartalarm/smart-sleep-smartalarm/Backend/sensors/sensors.py

You might want to have files run automatically each time you power up your RPI so that it can fully run headless.

To do this we'll need to create 2 .service files

API service file

Run the following

sudo nano /etc/systemd/system/smartalarm-api.service

and paste

[Unit]
Description=SmartAlarm API
After=network.target
[Service]
ExecStart=/usr/bin/python3 -u /home/smartalarm/smart-sleep-smartalarm/Backend/api/app.py
WorkingDirectory=/home/smartalarm/smart-sleep-smartalarm/Backend/api
StandardOutput=inherit
StandardError=inherit
Restart=always
User=smartalarm
[Install]
WantedBy=multi-user.target
Device service file

Device service file

Run the following

sudo nano /etc/systemd/system/smartalarm-sensors.service

and paste

[Unit]
Description=SmartAlarm Device
After=network.target
[Service]
ExecStart=/usr/bin/python3 -u /home/smartalarm/smart-sleep-smartalarm/Backend/sensors/sensors.py
WorkingDirectory=/home/smartalarm/smart-sleep-smartalarm/Backend/sensors
StandardOutput=inherit
StandardError=inherit
Restart=always
User=smartalarm
[Install]
WantedBy=multi-user.target

then enable both service files by running the following

sudo systemctl enable smartalarm-api.service

sudo systemctl enable smartalarm-sensors.service
