Good communication is important in any relationship. I wish my plants were better at it.
I’m building a spark-core-based all-in-one garden monitoring system. It will send temperature, light, and soil moisture readings to a phone.
On my flight to Minneapolis, I sat next to a guy named Dan. Dan is involved in community based agriculture but was struggling to find sensors available at a low cost. I think the idea of a DIY open source sensor would be terrific. More inspiration came from my own experiences/failures with gardening: This is one of two plants I own that is still alive (thanks Martin!). The other is a cactus. I started with five plants.
I’m starting with an arduino and then moving to the core.
I envision it as a 3 prong stake. Two prongs for the resistance based moisture sensor, a third for the soil temp since soil resistance will change with temp. Light sensor placed on the side because incident light is a better measurement for my purpose. There will be a solar panel…somewhere.
I looked at GardenBot (a great open source gardening system), seeed studio (open source moisture sensor), and adafruit (for help with the temp sensor). I’m using gardenbot’s moisture sensor circuit for my prototype but will be modifying seed studio’s moisture sensor for the final ver.
Coming up… I’m going to layout a PCB and get things set up on the core.
feedback/questions/comments/whateva super welcome
Hello! I’m Ramya. I’m interning / hanging out with the Spark team in Minneapolis for a few weeks. My role is to use the core in 1-2 projects, give feedback, and leave the real hardcore work to the other team members. I’m going to use this post to keep you updated on my first project.
