[Pool Water Monitoring] #10 Architecture Design: Sender, receiver and display

Hi all !

Happy New Year to all. Hope everyone is safe and sound.

Today, I'm presenting in more detail my design for the challenge.

NOTE: This will be updated with the links to the respective blog entries when done.

Project

This project is comprise of 3 parts, each one with its own set of challenges

  1. Data collecting
  2. Data receiving
  3. Data sharing/display

Here's a diagram of the entire design

Design Diagram

It will be using most of the Kit hardware and a few of my own.

I'm going to write about all of them in separate entries, but here's a brief summary:

Data collecting

In data collecting, we will gather all the values from the monitored environment and send them via LoRa to the receiving end.

Will will be measuring:

  • Water temperature
  • Water TDS
  • Water PH
  • Ambient Temperature and humidity

All of this will be inside of the Hammond enclosure with the transparent lid.  The cables will be outside by means of one of the Hammond cable glands.

The following blog entry details this design

Data Receiving

The other Arduno MKR 1300 WAN will be receiving the data and will be doing three things:

  • Send data to the Arduino IoT Cloud
  • Send data to Twitter
  • Send data to the Arduino UNO to be displayed on the LCD RGB and any warning on the LED

The received data will be here analyzed and watch for values outside the normal values.

[The following blog entry explains the water parameters that we are we looking for and why]

The following blog entry details this design

Data sharing

Although it's described above, this deserves its own blog post for the detail on how it's sent to both Arduino IoT Cloud and Twitter.

Happy New Year everyone.

Stay safe

    Thank you ! I probably would connect it directly to the Arduino without thinking about that - because in a previous work, the Arduino was 5v ! :)

    It will be interesting to see how well your ph probe holds up.

    Oooh and whislt I think of it, be careful with the pH probe, this really wants a 5v supply to it (even tho it tells you 3.3-5.5v). The MKR1300 pins are only 3.3v tolerant, anymore than this and you are going to let the magic smoke out at worst.

    I have experimented with runing it at 3.3v but did not get a repeatable/stable measurement from it. The 3.3v limit on the MKR boards almost caught me out!
