Progress report (Feb. 27 2017)

December 2016

Ordering of components on Adafruit with the USD 150 gift.

January 2017

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

  • 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).
#define RF95_FREQ 868.0
  • Add the blinking LED on pin 13 on the TX device
digitalWrite(LED,packetnum%2);

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

Soil and Temperature Moisture

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

Data processing and visualization

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 :
