Story

Our story have started in 2017, when my friend, and our honorable member of the team, worked in McDonald's, where he noticed that managers waste a lot of time on filling the HACCP papers, counting goods and checking their expiracy date. Today we are trying to create a smart logistic system, which should help them.

Our system has two major functions. The first, of course, is storing data about goods and the second one is logging their storage temperature, which is important accourding to HACCP law.

1. Hardware build

To construct this solution, you need to use following parts: BigClown GPS module, BigClown core-module NR, BigClown LoRa module, BigClown sensor module, BigClown mini baterry module, DS18B20 Temperature Sensor.

You can see how to put together the construction down below.

2. Flash firmware

Download BigClown Playground.

Download project repositority with this binary.

And Flash it!

3. Database

On our server, we have a microservice, which uploads data from CRA cloud to our Firebase database. It representes fast data managing in realtime. We have chosen cloud platfrom to make sure that data are ready anytime.

For example you can use our prototype LoRa decoder and forwarder to MQTT from this repository. You can send data to for example Google Firebase instead sending data to MQTT broker.

4. Dashboard

We are using our self-designed dashboard, which is based on plain JavaScript and some of its libraries, including ChartJS, jQuery, Moment.js and Cookie.js. The dashboard itself shows all the maintained storages and it's data along with graphs.

You need to download our whole project and just run "index.html". That's all. After this, you will juste paste your unique EUI in the pop-up and you will see the whole dashboard running

5. Mobile Application

Our mobile application is made in Xamarin.Forms.

You need to download the application to be able to add, remove or view the registered devices - storages and its goods. You can download the project here: https://gitlab.com/lisoft-at-t-hackathon-2019/lisoft-data-management. Don't forget to upload the project to your mobile device.

Summary

This project offers an easy, wireless, low-power solution for companies or small stores which are using any sort of storage and logistics system. It tracks current temperature, its history, number and amount of products.
