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
  +

The project started on January 9th, 2017.
  +
  +
== Week 1 (January 9th - January 12th) ==
  +
  +
* Project selection ([[Projets 2016-2017|List of all subjects]])
  +
  +
== Week 2 (January 13th - January 19th) ==
  +
  +
* Introduction to LoRa by [[User:Donsez|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 20th - January 26th) ==
  +
  +
* 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 [https://en.wikipedia.org/wiki/Duty_cycle duty cycle] (1% of the time)
  +
* The meeting was canceled by the managers of the farm and reported to the [[#week5|8th of February]]
  +
  +
== Week 4 (January 27th - February 5th) ==
  +
  +
* No official time slot for the projec this week (Postpouned)
  +
* Call with Vincent Hibon on the 1st of Feb. We spoke about the advancement of the project.
  +
  +
== <span id="week5">Week 5</span> (February 6th - February 12th) ==
  +
  +
* We got some new hardware : ''[[Mbed]] SX1272'' with a [[STM32_Discovery#Cartes_Nucleo|ST Nucleo]] board, therefore we have to re-setup our computers to makes these cards working. Adafruit cards will be given to the [[Projets-2016-2017-I-Greenhouse_:_Serre_connectée_aquaponie|project n°2]].
  +
* On wednesday afternoon, first meeting at the farm with Vincent. We also meet Isabelle, Vincent's wife, the manager of the farm. Here is a [[Media:Recap_visite_ferme_-_08_02_2016.pdf|report]] of this afternoon (in French).
  +
* There are some pictures picked today (yes, the forecast wasn't very good...) :

  +
  +
== Week 6 (February 13th - February 19th) ==
  +
* Monday:
  +
** We are very disheartened with these new STM32 cards. Three other hours lost in making research about how to make it works.
  +
  +
* Tuesday:
  +
** Nice day ! Finally STM32 worked today, we were able to run the "PingPong" example program ([https://developer.mbed.org/teams/Semtech/code/SX1272PingPong link]) and exchange some data
  +
** We are able to transform voltage from the temperature sensor[http://wiki.seeed.cc/Grove-Temperature_Sensor_V1.2/] to degree celsius.
  +
** ''NB: We use <code>picocom /dev/tty.usbmodem1423</code> on macOS 10.12 and Putty (<code>/dev/ttyACM0</code>) on Ubuntu to have a console output.''
  +
  +
* Thursday:
  +
** Didier Donsez gave us a new sensor that is able to record temperature AND moisture.
  +
** Setup NodeRed + InfluxDB (docker) in contemplation of this tutorial : [[Developing IoT Mashups with Docker, MQTT, Node-RED, InfluxDB, Grafana]].
  +
** We also speak about the [https://wiki.eclipse.org/Eclipse_IoT_Day_Grenoble_2017 Eclipse IoT Day Grenoble 2017] and sent mail to the Fablab in order to create a 3D Greenhouse in Plexiglass
  +
  +

Project presentation

Sky view of the exploitation (© Google Maps)

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

Documents

Calendar

The project started on January 9th, 2017.

Week 1 (January 9th - January 12th)

Week 2 (January 13th - January 19th)

  • Introduction to LoRa by Didier Donsez.

    • We are very disheartened with these new STM32 cards. Three other hours lost in making research about how to make it works.
  • Tuesday:
    • Nice day ! Finally STM32 worked today, we were able to run the "PingPong" example program (link) and exchange some data
    • We are able to transform voltage from the temperature sensor[1] to degree celsius.
    • NB: We use picocom /dev/tty.usbmodem1423 on macOS 10.12 and Putty (/dev/ttyACM0) on Ubuntu to have a console output.

Week 7 (February 20th - February 26th)

Week 8 (February 27th - March 5th)

  • Going to the FabLab in order to carve the model. The base is made of MDF (Medium-density fiberboard) and the structure is made of Plexiglas.
Greenhouse model

  • Set-up Node-red, we are able to retrieve data printed by the device (connected on /dev/ttyACM0)
    • The Extract data function :
1setTimeout(function() { node.status({}); }, 500)
2node.status({fill:"green",shape:"dot",text:"updated"});
3return msg;
Node-red dashboard

Week 9 (March 6th - March 12th)

  • Node-red, Mosquitto, InfluxDB and Grafana

Week 11 (March 20th - March 26th)

  • We are able to supply the nucleo cards with a solar panel.
The nucleo and its solar panel
Connection on the nucelo
  • We started to write our final report
  • Communication with Vincent Hibon about the project progress
  • Didier Donsez provides to us a MQTT server adress and topic. We integrated it into our node-red flows.

Week 12 (March 27th - April 2nd)

  • We created a node-red Dockerfile with our flows to simplify the installation on the farm computer : Github
  • Edition of our code Mbed
  • Think about optimization of data sent (Binaries instead of characters)
    • We were able to optimize. Now, instead of 1024 bytes, we send 6 bytes !
    • Here is our message cutting:
measurement 4 measurement 3 measurement 2 measurement 1 measurements types greenhouse informations
47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
  • Greenhouse informations (0 to 7):
    • Bits 0 to 3 represents the greenhouse number (Can be 0 to 15)
    • Bits 5 and 4 represents the sensors positions in the greenhouse
      • 00 -> extremity 1
      • 01 -> middle
      • 10 -> extremity 2
    • Bits 7 and 6 are not used (have to be 0)
  • Types (8 to 15):
    • Bits 9 and 8 represents the type of the measurement 4, bits 10 and 11 the type of the measurement 3, ...
      • In this byte, all bits have a partner.
      • The first bit represent the measurement type
        • 0 -> Temperature
        • 1 -> Humidity
      • The second bit is the sensor type
        • 0 -> Air
        • 1 -> Soil
  • Each measurements (16 to 47) are encoded on 8 bits.
    • We transform our float to uint8 with a personal magic formula.
  • Preparation of the demo, final report and final slides
