Using a Raspberry Pi to Monitor Plant Soil Moisture
Ever had that moment when you realize your plant parenting skills need a tech upgrade? That’s exactly where I found myself when I started growing a citrus plant with a thirst that seemed unquenchable. So, I decided to build a system that could help me keep track of the plant’s water needs by monitoring the soil moisture levels using a Raspberry Pi, a soil moisture sensor, and some rust code. I know, I know, I could have just bought a moisture sensor and plugged it in, but where’s the fun in that?
Up until now, I’ve only ever built software projects so this would be my first hardware project (even if it is just plugging a few wires in and reading the sensor!).
In this post, I’ll walk you through how I built a plant moisture monitoring system using a Raspberry Pi Zero W 2 and a soil moisture sensor, and how you can build one too.
Since I have never soldered before, I chose the model that comes with the headers pre-soldered, but you can choose the one without the headers if you’re comfortable soldering.
