UnifiedWater

I went around to collect some data from the device and ensure that everything is working fine. I started off by heading to a canal near me and leaving the device in the water for around 4 hours and collecting the data sent back. I noticed that the pH reading was very bad and tested the pH probe to see what reading it gave when I put it in distilled water. Because the reading was not 7, I had to recalibrate the probe by leaving it in the distilled water until its reading was of pH 7.

I then headed closer to the City Center. I walked around tributaries of the River Liffey (Dublin) and placed the device in the water to take a reading at different points. I then collated this data in a dashboard I created using Soracom Lagoon. I found that one of the readings showed a bad pH value in one of the tributaries of the river.

Because of the time constraints, I had to get creative with the enclosure for the project. I have to admit that this isn't the most appealing enclosure I made up to date but it does get the job done.

I started off with pieces of piping cut into different sections. I then glued them together and insulated them.

After that, I placed all the components within the enclosure and sealed it off.

I worked about 3 weeks on the code for the project. I split the task into multiple code versions ranging from initial drafts where the sensor data would be read and stored in local variables to sending this data to the backend. I then published the final version of the code on GitHub

I received the components over the next couple of weeks. I then started building the project. I started tinkering with each component separately trying to understand them and interface them with the Arduino. I had to calibrate the pH sensor to ensure that its reading was precise at this time. I then started working on the final version of the code amalgamating all components together in the project.

The next thing I did was order all the components I needed to build the project. The list of components is displayed in the project's story. I bought the majority of them off Amazon because of their fast shipping time.

I had some of the components such as the Arduino MKR GSM already as I used them in previous projects.

I use MS Whiteboard to sketch out ideas for the projects I make and bring everything together there. I finished planning the project about 2 weeks after I came up with the idea for it. I had planned out the project timeline, the tasks I needed to do in order as well as a list of components I needed to buy to compile the project.

Hi there,

Because I am migrating this project from another website, I already did everything included in the logs a while ago. So I am writing all of the logs today highlighting the main events and troubles I faced while developing the project.
