My home tempearture sensor for my RaspberryPi
Project description
One Home Sensor
This peace of software reads temperature, pressure and humidity from a BME280 sensor. It then pushes the result to a MongoDB data-base (MongoDB Atlas form my part).
Usage
My setup is as followed :
+-------------+
| RaspberryPI | +-------------+ +-------------+
| | | MongoDB | | Phone / |
| one_home_ +--->| Atlas +--->| WebBrowser |
| sensor | +-------------+ +-------------+
+-------------+
I periodically run it (throught systemd) to store the values.
Integration / Instalation
This programe is created and only used/tested/supported in python3. These commande should solve all dificulties.
sudo apt-get update
sudo apt-get install python3-setuptools python3-pip i2c-tools
- Create cluster on MongoDB Atlas
- Create connection autorization and user
- Create configuration file (see next section)
- Enable I2C in raspi-config (5 then P5).
- Add user to group "i2c" (sudo usermod -a -G i2c leadthesalt)
Finaly the module is installed with pip3.
pip3 install one-home-sensor
For my part I install the programe with an Ansible rôle. Sure I could create a debian package, but I only use it on my Raspbery Pi that are already managed throught Ansible.
Configuration file
[MongoDBAtlasConnection]
username = # username set for MongoDB
password = # password set for MongoDB
clusterfqdn = # fqdn to MongoDB server
