Progress report (Feb. 27 2017)

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

• 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

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).
