Projets-2016-2017-Serres connectées

= Project presentation =



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

 * 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

Week 4 (January 30th - February 5th)

 * Call with Vincent Hibon on the 1st of Feb. We spoke about the advancement of the project (more details will come).

Week 5 (February 6th - February 13th)

 * We got some new hardware : Mbed SX1272 with a ST Nucleo board, therefore we have to re-setup our computers to makes these cards working. Adafruit cards will be given to the project n°2.
 * First meeting at the farm with Vincent. We also meet Isabelle, Vincent's wife, the manager of the farm. There are some pictures picked today (yes, the forecast wasn't very good...) :
