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

Calendar

The project started on January 22th, 2018

Week 1 - 22/01/2018

  • Getting to know the nucleo card :
    • We tried online mbed compilation tools
    • We manage to cross-compile locally on Arch Linux and deploy on the card
    • We transmitted data betwteen two LoRa card using peer to peer transmission
    • Using the Lora module OVER the nucleo extension card is not currently working.
  • Zenkit agenda created

Week 2 - 29/01/2018

  • Contacting the IESE group
  • More in depth understanding of the project objectives
  • Begin the docker documentation reading
  • Store and display data specification
    • InfluxDB
    • Graphana

Week 3 - 05/02/2018

  • Git Repository creation
  • Added our Zenkit backlog to the wiki
  • Testing Pico Lora Gateway
    • Flashed the gateway (the software was outdated, leading to an error)
    • Configuration tuning to match the "Ping Pong" test software.
    • Testing the gateway with the logger utility
    • Forwarding the packet with the picoGW_packet_forwarder
    • Successfully retrieved a "Ping" (conversion base64 to ASCII)
    • Only work when sending a great amount of packet: lot of loss ?

Week 4 - 12/02/2018

  • Spent lot of time on the gateway
    • Huge amount of packets were lost beforehand
    • PacketForwarder configuration file and source modification to have coherent frequency, spectrum ...
    • All packets can now be forwarded to a UDP server (local in our case)
  • Started to have a look on Node-RED
    • We received JSon from the gateway
    • We are able to decode the base64 payload
  • SRS and UML added to the wiki

Week 5 - 5/03/2018

  • Started to work on automatisation with Docker
    • Using DOcker Compose
    • Optimization of container with special iage for compilation
