The project subject : Serres connectées.

The project consist of upgrading a classic greenhouse to retrieve live information about its climate. The farm exploitation is located in Saint-Cassien (38500), in the French Alps.

Data to retrieve :

Air temperature
Air moisture
Soil moisture

Control of these parameters are essentials to avoid disease, enhance the growth of the plantations and limit water consumption.

Two main constrains :

No power in the zone
Sensors needs to be moveable to let vehicles move along the greenhouse

Team

Supervisor: Nicolas Palix and Vincent Hibon

Members: Antoine Boisadam, Oriane Dalle

Department: RICM 4, Polytech Grenoble

The project started on January 9th, 2017.

Week 1 (January 9th - January 15th)

Project selection (List of all subjects)

Week 2 (January 16th - January 22th)

Introduction to LoRa by Didier Donsez.
Discovery of the project
Setup of our computers to be able to program our Adafruit Feather.
First Hello world with the hardware (Discussion between two Adafruit Feather 32u4 in LoRa)
Call with one of the managers of the farm, Vincent, the feeling is good with him, we spoke during one hour :
- He spoke about him and his wife farm exploitation
- He detailed the farm layout
- We asked him some precise questions about the project (Types and numbers of sensors wanted, data wanted, ...)
- We agree on a meeting for the next Wednesday (25/01/2017)

Week 3 (January 23th - January 29th)

Define the use case diagram
Taking charge of the Adafruit Feather card and the PyCom one.
We wrote a little program that is able to send and receive data. At the moment these data are fake temperature until we embedded real sensors
We determinate the length maximum of data that we can sent to be able to record data each 30 minutes and respect the duty cycle (1% of the time)
The meeting was canceled by the managers of the farm and reported to the 8th of February
