I have a grow tent I want to throw a raspberry pi and some sensors/relays in. I don't really have a plan as much as a bunch of spare parts I need to find a use for. I'm excited to see what it turns out to be.
This is a work in progress - I will update the logs as I go in a blog style format.
I have a feeling it gets to cold in the tent. I wrote a python program to read the temperature inside the tent, compare it with the lowest previously recorded value and overwrite if current value is less than the previous value.
At some point I'm going to expand on this and use a csv file with matplotlib to create graphs of this data. This should get me started and give me the information I need.
I'm using a cronjob to automate the task. Every 20 minutes it's running this check.
Inquirer is going to let me set up menus and prompts for the grow tools I'm creating. I've built a lot of system tools for myself and colleagues using inquirer and node.
I've been using mobaXterm community edition to remotely access the pi and have become a huge fan of all the features it gives me. With the shell it also gives me a GUI to explore the folder tree and I just found out if I save a picture made from matplotliblibrary I can click and view it through mobaXterm - Really cool.
I want to have a 24 hour graph made with current info. Each 24 hour period should be saved to a folder with its name as it's date.
I want to use a capacitive moisture sensor from Adafruit to get soil moisture levels
I want to hook up a pump and reservoir for automated watering
I need to set up ventilation. Right now I open the tent when the lights are off. I'm looking at blower fans for around 70 dollars. I'd like to program the pi to work with a relay and turn the fan on for about 20 minutes then shut them off for an hour - and repeat.
What are you growing?
