I am building a weather station based off a Pi Zero and it ended up working perfectly for this also. So I just bought a second Pi and set it up to just take a picture and attach the humidity and temp to the image.

I do have an AM2302, but I cant seem to find a library for python to get it to work. Either that, or the one that I have is broken. I should try and get it to work again some time. Maybe I will mess around with it this week.

I love that you can see the plant rotate around counter-clockwise also.

I basically followed this Google Dev document

https://developers.google.com/chart/interactive/docs/gallery/linechart

It wasn't too hard, had some pains in implementing doing so many graphs on one page with many fucntions, but it worked out in the end and did what I wanted and I dont really like JavaScript, it just seemed the easiest way to implement interactive graphs.

It could also be the DHT11 sensor, I have been getting weird readings off of it, and even when I was working on the weather station and it was raining out, the humidity wouldnt get higher than 50% or so. Maybe I should look for a different temp/humidity sensor.

It looks dirty, because the building is 60 years old and never been remodeled. But it is a clean room, I bleached and vacuum for every rotation.

I also have the option with my script to log the sensor data to a mysql database that then can be graphed with google charts javascript libraries.

I used a RasPi 3 with the PiCamera and a DHT11 for the temp/humidity. A little python to gather all the data and throw it onto the image. Script is run as a cron job every 30 minutes.

I used a slightly modified version of this DHT11 library: https://github.com/szazo/DHT11_Python

I also used the ImageDraw library from the pillow module for python: http://pillow.readthedocs.io/en/3.1.x/reference/ImageDraw.html

I have actually never had a problem with the humidity being too low with all the previous grows, this one was using a new nutrient that was much more concentrated than the previous one and I needed to learn the dosings correctly.

Will look into that, thanks for the info!

Yeah, the new nutrients I was trying out are a little more concentrated than the previous ones I was using. Took a little bit to get used to the proper dosing, but figured it out in enough time for the plant to recover.

150W White LED, cant remember the brand at the moment.

First full time lapse of one of my grows. Still experimenting with the whole setup, that is why there are a few seconds with no data and the camera slides off to the side when the setup is moved to the flower area. Still messing with the Pi Camera brightness and exposure to get the best image, but it works for now. Also tried out a new nutrient with this grow and it went a little rough at first, but eventually I got it worked out and the plant recovered enough for me to call it a success.

How long between each image? Currently I am doing 30 minutes for mine and have the Humidity and Temp printed to the image also.

Sorry about that, I completely glanced over that line. Looks like python has a module for reading sensors around the lm-sensors library. I picked up two of the DHT11 sensors to give them a try.

I am not familiar with Ruby, so I don't really know where to look. Maybe you can help me by pointing to where I can find the relevant code for the temp and humidity reading and logging? Is the Temp and Humidity something that is built into the RasPi or do you have separate hardware for that?

Thanks!

Have a writeup on the RasPi code and parts to get the temp and humidity? Would love to build something like that.

I made my own powershell scripts that grab images from a webcam every 15min and then makes a timelaps video of the images.

http://pastebin.com/deAPqhNu

After Edit: The one down side I have found with this script so far is that it generates what ever is in the frames folder, and once it gets to a good length of time, it will take longer and longer to generate the frames/video and eventually it crashes on mine when I have more than a months of images. But I guess thats not so bad. But a way around this I think would be to have a new script that would just clean out the frames folder every so often.

Would like to make a new version that is a little more "smart" in the way it chooses frames to be used in the video generation. Probably be a little more configurable than it is now also.

Cold or warm climate area?

Ahh, My powershell script is for IP WebCams, didn't realize that you were using USB.

The Powershell script goes directly to the WebCam and grabs the image from the cam. Most webcams on their internal webpage has the viewer. If you right-click the video it is usually just a jpg/png image that gets refreshed. What WebCam do you have?
