RICM4 2017 2018 - Serre Connectee

= 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

 * How to restart the docker if necessary :

- Connect with ssh to the raspberry ( user: pi password : pi) - execute these commands : $ cd docker-fullstack-JDC $ docker-compose down $ docker-compose up -d


 * Installation for the demo:

 * Follow this tutorial :

/!\ Use https://gricad-gitlab.univ-grenoble-alpes.fr/Projet-RICM4/17-18/11/serres-jdc/tree/master/docker-fullstack-jdc instead of the link provided in the tuorial

$ sudo vim /etc/hostname and $ sudo vim /etc/hosts $ sudo apt-get install avahi-daemon Finally, reboot the raspberry.
 * Optional (to rename your raspberry name and address) ->

You're done

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 * Flashed the gateway (the software was outdated, leading to an error)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 image for compilation
 * External sensor is now working and sending data
 * Searching for appropriate library
 * Plugged into the numerical pin on the lora board
 * Demo preparation for the JPO
 * Simple POC (still not encoded properly)
 * Using a Raspberry Pi
 * Result displayed on Graphana (temperature & humidity)

Week 6 - 12/03/2018
Finalize demo for JPO
 * Grafana configuration
 * Change mbed code formatting / code cleaned up for different sensors
 * Docker image with all configuration generated

Week 7 - 19/03/2018

 * Test gateway reliability : losing 1/5 packets
 * Test docker image on Armv6 and x86
 * Test with different time interval
 * Test with different power dBm
 * We didn't manage to identify the problem
 * Radio configuration ?
 * Wave interference ?
 * Searching for documentation about eeprom flashing
 * successfull read and write on the eeprom
 * started thinking about the protocol of pre-configuration

Week 8 - 26/03/2018
Preparation for on site integration
 * Creation of a new docker image with everything built for arm (grafana on the pi)
 * Test and installation of Avahi (Zeroconf) for static local domain name for the pi.
 * Protocol modification to have greenhouse id in the payload : end up in one graph output per card.
