After a couple months, H2OSupport’s first prototype has ultimately been finalized. The device’s main features are to collect interesting water quality readings (at home or on the field), evaluate them both individually and as a whole as well as display and save the data online. The project also implements handy online alerts that notify theContinue reading “Final Look – 28/08/2021”

A massive part of the project is organizing all of the collected readings and visualizing it. That is what Soracom Harvest and Lagoon are perfect for. Since the chosen SIM for H2OSupport is provided by Soracom, it is very easy to connect and setup these two pieces of software. Soracom Harvest is a platform whichContinue reading “Soracom Harvest and Lagoon – 26/08/2021”

H2OSupport can read and collect data very efficiently, the modern analog sensors get more and more precise every year and the digital sensors can do the quasi totality of the work. But what about H2OSupport’s ability to connect to a certain network and transfer all of the data? The MKR1500 has an on-board U-blox module,Continue reading “U-blox and the Cat-M1 Network – 22/08/2021”

Firstly, the battery that was intended to be used for H2OSupport fits in the plastic box, but leaves few space for the rest of the components. I’ve decided to go with a obvious second solution, a classic 9V battery. This will provide enough voltage for all the sensors as well as last a pretty longContinue reading “Making Small Amends – 19/07/2021”

I’ve just discovered that the SIMs from Soracom don’t support NB-IoT yet, so they can’t connect to the narrowband network. They redirected me to Rogers, saying they are the only Canadian IoT provider that has NB-IoT (Cat-M2) coverage. I’m currently trying to obtain an NB-IoT SIM card from them. If Rogers can’t provide a SIMContinue reading “New SIM Plan and Other Updates – 14/06/2021”

To interact with all the different sensors, we’ll have to write some code. It will essentially retrieve data from all the different sensors, using libraries specific to each sensor. Since this is an Arduino project, I’ll be coding sketches with the Arduino IDE [1], which uses a language called Processing that is based off ofContinue reading “Setting Up the Arduino IDE – 04/06/2021”

Looking at H2OSupport from a software perspective, there’s two sides, commonly called front-end and back-end. The front-end side of the project is composed of how the device will collect the data, which means writing code for processing and transferring the data from the different sensors. The front-end also includes how the data is presented toContinue reading “Connecting to the IoT – 27/05/2021”

The Arduino MKR NB 1500 board requires a constant ~3.3V power source to operate, common boards usually have a micro-usb input port, just as this one does. Since H2OSupport will operate in remote locations (places where it will not be close to a power source), the device has to be powered by a portable battery.Continue reading “Battery Power – 26/05/2021”

Arduino To start working on the project, it would be practical to have an Arduino board. Arduino sells multiple types of boards, which can all complete the same basic tasks, such as sending signals to light up small LEDs or retrieving data from analog sensors. However, all their boards are different, from some boards beingContinue reading “Arduino and IoT – 19/05/2021”
