The scripts in this project are used to collect data from the sensors of a Greenhouse and send them to an InfluxDB instance.
The script should run on Raspberry Pi devices (Data Collectors), which are physically connected to the sensors and virtually connected to the InfluxDB server.
The sensors retrieve data related to:
- Light intensity of the greenhouse (in lux)
- Temperature of the shelves in the greenhouse (in °C)
- Humidity of the shelves in the greenhouse (in %)
- Moisture level of the pots in the greenhouse (in %)
- NDVI of the plants in the shelf (between -1 and 1)
To run the code needs the following packages to be installed (used for the NoIR camera):
sudo apt install -y python3-pyqt5 python3-opengl build-essential libcap-dev libcamera-devTo install the python dependencies, run the following command from the root of the project:
pip install -r requirements.txtModify the config.ini.example file to set the URL of the InfluxDB server, the personal access token and the organization ID. Save the file as config.ini in the collector folder.
For other optional parameters, see the documentation.
You can set the raw voltages reading of the sensors, so they can be converted to meaningful values. The array can be of arbitrary length and will be mapped to a range of 0 to 100
To run the main script, run the following command from the root of the project:
python3 -m collectorTo execute a demo, run the following command from the root of the project:
python3 -m collector --demoThe demo will create a database named demo and will populate it with pot measurements with decreasing moisture, simulating a real life scenario which triggers the actuator to water the pot.
The measurements refer to a pot with
- shelf_floor = 1
- group_position = left
- pot_position = right
- plant_id = 1
The incoming modifications to the configuration file are made using the message broker, for which the .env file must be configured with the correct credentials.
