Story

1.0 PROBLEM STATEMENT

In rural communities across Nigeria, farmers want to know how to increase their yield considerably, especially with the effect of climate change. Local farmers want to know when, where, and how to do this at the most affordable cost. How they can do it without having to call in a specialist which in itself is costly?

The nutrients in the soil are determined by many factors ranging from nutrient depletion due to usage, and environmental factors such as pollution. This affects the production yield when its time for cultivation which brings about low farm yield considering that greenhouse farming is considerably expensive in these parts of the world.

2.0 PROPOSAL & SCOPE

The goal here is to collect soil/environmental data and send this information to the cloud and we process them via an ML algorithm to determine if they need certain nutrients to produce a viable crop yield. This will then be sent to the owner as a notification to either up a specific nutrient composition or not through a mobile application.

The initial idea was to use LoRa which covers a considerable area network but was limited by the gateway which was unavailable in this part of the world. Using the ever-present WiFi network we were able to send the soil/environmental conditions data To AWS via the IoT core using the SenseCAP K1100 provided by Seeed Studio.

3.0 HOW TO

This project is divided into 2 sections:

Data collection
Connectivity

3.1 DATA COLLECTION

We enjoyed this project because this is the first project we've had with respect to agriculture and using the SenseCAP K1100 was a thrill.

Setting up the SenseCAP K1100 via the Arduino IDE was pretty straightforward, which allowed us to connect to the Wio terminal and flash before the coding begins.

The system was set up to collect humidity, ambient lighting, temperature, and moisture and display these figures on the LCD screen. All of this is configured on the main Arduino code.

1 / 2 • LCD display of soil data collected

3.2 CONNECTIVITY

In other, for this device to send this data to the cloud there had to be a connection with an internet source and a cloud architecture. In this case, we made use of the AWS cloud and the AWS IoT core, which was quite simple to get around, especially as we used MQTT as the transport channel.

Create a certificate with AWS IoT core
Store this certificate in config.h file in the Arduino IDE

CONCLUSION

As I said before the connectivity of LoRa/Helium had been the major issue we face but overall it was a nice experience working out a solution to send soil data to the cloud. In the future, we look to send this data through an ML algorithm and proffer solutions to the small-holder farmer via either a USSD message or mobile application.

// Attach this header file to your sketch to use the GFX Free Fonts. You can write

// To save a lot of typing long names, each font can easily be referenced in the

//
//    1. Font file name with the & in front such as &FreeSansBoldOblique24pt7b
//       an example being:
//
//       tft.setFreeFont(&FreeSansBoldOblique24pt7b);

//       an example being:
//
//       tft.setFreeFont(FF32);
//
//    3. An abbreviation of the file name. Look at the list below to see
//       the abbreviations used, for example:
//
//       tft.setFreeFont(FSSBO24)
//
//       Where the letters mean:
//       F = Free font
//       M = Mono
//      SS = Sans Serif (double S to distinguish is form serif fonts)
//       S = Serif
//       B = Bold
//       O = Oblique (letter O not zero)
//       I = Italic
//       # =  point size, either 9, 12, 18 or 24

//  Setting the font to NULL will select the GLCD font:
//
//      tft.setFreeFont(NULL); // Set font to GLCD
