Hello OpenAg Community!
I have a challenge before me to create a hermetically sealed grow environment for research. This chi square study involves multiple environments with a high degree of environmental accuracy. The nature of the study demands that data is collected from many remote, distributed endpoints to one data center.
Environment is 78"x78"x78" mylar tent. Goal is to gather telemetry and control multiple environmental system for plants in soil
One issue I see is controlling irrigation to each pot to proper soil moisture tolerance. Originally considered amalgamating 16 soil moisture meters to collect the average and irrigate accordingly with the 16 channel relay. Controlling nutrients with peristaltic pumps and irrigation reservoir.
Then someone blew my mind and said, to do this properly, each pot needs independent IO. I’m not sure how I can do this, but I was thinking about a bunch of solenoid valves.
Seeing my tasks multiply, I am calling out for assistance from this community for design considerations and help modifying the software.
My BOM is essentially a modified PFC BOM v2.0 (alpha) with exception of probes, hydro nutrients, materials for enclosure, OpenAg and environmental outputs. Add 6000 BTU AC unit, dehumidifier, weatherproof box, 7" TFT, 25A solid state relays, several tamper proof power outlets, and many soil moisture sensors. Have this BOM x 2 at my house. Boxes everywhere.
I ordered a couple of helper boards from PlantCubed last week. I am hoping this will meet the connection requirements for sensors and relay board.
Currently drilling holes in the weatherproof box to install sensor leads and power outlets for lights, AC, dehumidifier, etc… Modeling it after the brain_box.
However I do this, I need something simple and quick. Any recommendations are uber appreciated.
