Background

Initial Design

I am currently working with a team from Codettes foundation( which is an initiative I started about a year now to inspire educate and bring awareness to girls in innovation and ict http://www.codettes.org/) to upscale a previous IOT for Agriculture Solution which we had developed in the Kosmos/IT-Core HackOmation 2018 in Paramaribo Suriname. My team had built a fixed iot solution for monitoring and controlling a small scale farm at the Local Kosmos/IT-Core HackOmation 2018 in Paramaribo Suriname but then we encountered the problem of what is going to happen if someone wants to use that same system to monitor and control a medium or large scale farm how were they going to do that.

My team and I then designed a open layered architecture where instead of having our sensors directly connected to our mcu and directly connected to our gateway which we were using an raspberry pi 3 with loraWan we were going to make these sensors wireless eliminating the wires and make them communicate over some sort of communication layer (which we in the end decided to use lorawan for covering wider range when sensing on a large scale farm or wifi for small and medium scale farms) and then the data is monitored and controlled centralized via a mobile or web dashboard. By having these sensors modular and wireless and having them communicate to a centralized platform we can solve the problem of covering small medium and large scale farm with the same iot solution.We were no longer fixed to cables or having to run long cables all the way to the back of a farm to do simple sensing or controlling.

Initial Architecture

Final Architecture

Who will use it?

  • Home/Hobbiest farmers , small and medium scale farmers
  • What will it look like?

  • The casing will be made out of wood or plastic.
  • I will be focusing on making the case look very similar to a stick from an actual tree so that it can blend into the environment when placed in the soil to monitor soil moisture..I will be using a 3D and 2D softwares to design and make my enclosure.
  • What does it do?

  • Greentubes sensor node1 is used to monitor temperature humidity and soil moisture. levels of your plant
  • Greentubes sensor node2 is used to switch irrigation pump on and off
  • Sensor 1 and 2 sends their data and can be controled via Greentubes centralized dashboard hosted on the gateway which is the raspberry pi
  • Users can easily monitor and control their farms over a cloud connected dashboard
  • Weeks Worked on Final Project

  • Week 3 CAD Redesign Version 1.0
  • Week 8 CAM Design and Build Plant Bed
  • Week 14 Networking and Communication /Tested Communication of Gateway and esp8266 wifi module
  • Week16 Interphase and Application Programming /Build my dashboard for my Gateway and tested communication of my nodes
  • Week 18 Selected the licens for my project
  • Bill of Material

    Bill of Materials 2 Sensor Nodes

  • c) what materials and components will be required?
  • d) where will they come from?
  • e) how much will it cost?
  • The answers to the questions above will allow you to create your BOM, or Bill Of Materials.
  • Material Purpose Quantity Price Origin

  • Work Done by others

  • Mqtt github repository and sample code for my stack Mqttjs
  • Amazing work done by Benjamin M. Mqtt Gateway
  • I couldnt have done it without the help of my classmate theoboomsma and local instructor Juan Carlos
