December 2016
Ordering of components on Adafruit with the USD 150 gift.
 * 3 Adafruit Feather 32u4 RFM95 LoRa Radio
 * Soil Temperature/Moisture
 * DS18B20 - Temperature sensor
 * BMP183 SPI barometric pressure sensor
 * I2C barometric pressure and temperature sensor

January 2017

 * Reception of the components
 * Soldering of the 868MHz antenna and the pins on the Adafruit Feather




 * Follow the Hello World example at https://learn.adafruit.com/adafruit-feather-32u4-radio-with-lora-radio-module/using-the-rfm-9x-radio



digitalWrite(LED,packetnum%2);
 * The TX device is connected to a solar panel with a battery pack (3x 1.2V)
 * Use the 868Mhz frequency to match the antenna capability (Available ISM in France).
 * 1) define RF95_FREQ 868.0
 * Add the blinking LED on pin 13 on the TX device

Air Temperature and Pressure
Use of a BMP183 (SPI Barometric and temperature sensor) connected to an Arduino Uno


 * 1) BMP183 3.3v <-> Arduino 3.3v
 * 2) BMP183 GND <-> Arduino GND
 * 3) BMP183 SCK <-> Arduino 13
 * 4) BMP183 SDO <-> Arduino 12
 * 5) BMP183 SDI <-> Arduino 11
 * 6) BMP183 CS <-> Arduino 10

Configure the Arduino IDE "Arduino" -> "Preferences..." -> "Settings"

Set the "Additional Boards Manager URLs" to the following https://adafruit.github.io/arduino-board-index/package_adafruit_index.json

Install the additional librairies "Sketch" -> "Include library" -> "Manage Librairies"
 * Adafruit Unified Sensor
 * Adafruit BMP183 Unified Library

Alternative installation from ZIP
 * https://github.com/adafruit/Adafruit_Sensor
 * https://github.com/adafruit/Adafruit_BMP183_Unified_Library

Soil and Temperature Moisture

 * https://www.adafruit.com/product/1298
 * https://github.com/practicalarduino/SHT1x

Use of a SHT10 connected to an Arduino Uno


 * 1) SHT10 Red 3.3v <-> Arduino 3.3v
 * 2) SHT10 Yellow (SCK) - S0 <-> Arduino GND
 * 3) SHT10 Blue (Data) - S1 <-> Arduino 13
 * 4) SHT10 Green (GND) <-> Arduino GND

Note the pull-up resistor on the data line (Blue and White).

LoRa communication tests

 * Communication between Adafruit Feather 32u4 RFM95 LoRa Radio and Pycom LoPy cards with a sending of simulated values
 * Code for Lopy : https://github.com/igreenhouse/picoloragateway
 * Code for Adafruit : https://github.com/igreenhouse/endpoints
 * Communication between two Mbed SX1272 with a "PingPong" program
 * Getting values from sensors and monitored by Adafruit Feather card

Data processing and visualization

 * First step with Grafana and installation of a test InfluxDB, Node-Red and MQTT (By following this tutorial Developing IoT Mashups with Docker, MQTT, Node-RED, InfluxDB, Grafana)

Mock-up

 * The project will be presented at the Eclipse IoT 2017 in Grenoble with a mock-up of the greenhouse.



Farm visit

 * Feb. 8, we visited a farm localized near Grenoble where we can implant the project. There are some pictures of the day with a satellite map of the exploitation :

Greenhouse model

 * Preparation of the mockup for Eclipse IoT Days Grenoble 2017
 * 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 PMMA (aka Plexiglas).
 * The mock-up's layout is available here : https://github.com/igreenhouse/Mock-up
