If you know anything about IoT development, you will know there is a large variety of hardware and devices available. Most are Arduino based, so share a common architecture. In Sogeti Ireland we have used Intel devices and RaspberryPi (is Pi IoT or not? That is for another day!). For this project we decided on an Intel Galileo Gen 2.
Intel have a number of devices which have starter kits for easy sensor assembly. The Galileo is the largest in a range of Intel devices, so we believe that we could miniaturise when required (we could also move to another manufacturer, after the PoC, but this worked for us and Intel have a good IDE and other features).
Next we had to think about the sensors. Like other boards, you can buy a sensor starter kit for the Galileo. The starter kit allows you to quickly and easily assemble the hardware (adding and removing sensors, without soldering, etc…) for your project.
We have found that the starter kits are great for PoC’s and prototyping but not for a final product. Firstly, the sensors are more expensive and most importantly, they are not calibrated correctly. I am also reliably informed that the circuitry does not use the best components and they are not properly shielded from each other. That aside, for a PoC, this was a good starting point for us.
Our starter kit did not have a Moisture sensor. So we purchased a cheap sensor online and our electronics guys wired it up.
What issues did we find and how did we solve them? [...]
