So, my wife wanted to have some small plants in the house. I didn’t, so we compromised, and got some plants. The only thing is that neither of us remembers to water them, so I wanted to build a sensor array to monitor the moisture content of the soil, and notify us when they needed watering.
We’ve got 3 plants, all fairly close to each other, and I wanted to create an IoT project so that it could send an email notification, as well as a visual ID when each individual plant required some TLC. Having worked with Particle.io before, I knew that a Particle Photon would be the best way to set it up.
This is a cool project and I amazed learning about the Particle Photon and mainly the power efficiency to enable it to be battery powered.
I have seen many plant sensor projects but was put off by the fact that you have to keep it plugged in.
I just purchased all of the items to build this. My first ever coding project.
Once I learn enough, maybe I will try adding a mini Peristaltic Pump to water it too.
In my research, I have found that the resistive sensors are not reliable and eventually corrode, even the gold immersion ones, and it’s best to use Capacitive ones. Can I replace the resistive sensors with a Capacitive sensor in this project? Will it need any mods to the code?
I am planning to use this one
