Building my own greenhouse data logger
A bad back threw out the opportunity to get digging in the greenhouse this weekend. Rather than sulking i ended up throwing this nifty little greenhouse data logger together. This will be a fun little project to develop over time and on those days i can't get out into the garden. (currently 6 of 7 😣) Eventually i'd like to be able to log on to view the data and even maybe have a camera setup in the GH to check in on my babies.... this could grow more out of control than the tomatillos i planted last year.
Anyway this is what I've done so far, and I've been too excited to not share it with you all!
What the greenhouse data logger is (currently) composed of.
- Wemos D1 Pro ESP8266 micro controller.
- Micro sd card slot to record data to (8gb card, enough for years of data)
- Real time Clock module for time stamping (and scheduling watering in the future)
- 2x DHT11 temperature and humidity sensors.
I ended up having to pull it out a few times to tweak code as its a mash of different sensors and the libraries required to run them, i ran into a few problems that were a PITA to find and fix due to the very poorly wrote code and copy and paste work from individual tests of the components.
So this is one of the first things i need to sort, clean up that code..
I did however manage to pull some data and put it into a graph. I'ts only 3 hours worth but i'm looking forward to have more to look over and see how things change over the coming weeks. Especially once i start finishing other elements on the greenhouse.
How i'm looking to improve the Greenhouse data logger.
- Clean up code of ease of trouble shooting/data formatting.
- Add in some averaging to avoid erroneous data.
- Work on a way to reduce power usage.
- Add in additional sensors (Light, Rain, soil moisture etc)
- Maybe Separate the data in to Day/night or daily logs for analysis and protecting data encase of data logger issues.
- optimise position of sensors or improve covers to avoid radiation heat influencing readings (if you look at the graph you may see a issue)
Question - What data would you love to know from your garden??? it'd be great to get some ideas on what other functions i may add over time.
And as always thanks for stopping by and reading the post. If you think it's worth it, don't forget to follow, like and upvote! But if you only do one thing leave a comment and say hello!
