This is an IoT project for home automation that include an Arduino and a Raspberry working together.
The Arduino Uno collects data from sensors and can start many smart routine.
The Raspberry shows the arduino data thanks to InfluxDB and Grafana. It also works as an alarm system,
when a movement is detected from the motion sensor, it takes a picture and sends it, with an advice, to your telegram bot.

To install InfluxDB add Influx repositories to apt:
wget -qO- https://repos.influxdata.com/influxdb.key | sudo apt-key add -
source /etc/os-release
echo "deb https://repos.influxdata.com/debian $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/influxdb.list
Upadate apt and install:
sudo apt update && sudo apt install -y influxdb
Start the influxdb service and set it to run at boot:
sudo systemctl unmask influxdb.service
sudo systemctl start influxdb
sudo systemctl enable influxdb.service
Run the inlux client with influx and create a user:
create database '<DBnamehere>'
use '<DBnamehere>'
create user '<usernamehere>' with password '<passwordhere>' with all privileges
grant all privileges on '<DBnamehere>' to '<usernamehere>'
show users
user admin
---- -----
'<usernamehere>' true
To install Grafana add repositories to apt:
wget -q -O - https://packages.grafana.com/gpg.key | sudo apt-key add -
echo "deb https://packages.grafana.com/oss/deb stable main" | sudo tee /etc/apt/sources.list.d/grafana.list
Update and install:
sudo apt update && sudo apt install -y grafana
Enable the service and set to run at boot:
sudo systemctl unmask grafana-server.service
sudo systemctl start grafana-server
sudo systemctl enable grafana-server.service
Grafana is now running on the machine and is accessible from any device on the local network.
Open a browser and go to http://'ipaddress':3000, where the IP address is the address that you used to connect to the Raspberry Pi.
Access the Grafana login page with the default username admin, and the default password admin.
Create a dashboard adding the graphs you need, remembering to select Influx as Grafana's data source.
Connect the DTH11 to Digital PIN2 and the InfraRed sensor to the 3rd PIN.
Load the sketch and connect the arduino directly to the raspberry.
Obviously you can add any sensor you want,remembering to update the files to make them capable to read the data and show them on Grafana.
You need to set your telegram bot token inside the main.py script togheter with a chat id to send the photo to only a specified chat id. You also need to set the correct parameters for connecting to the grafan server
