# Items Needed for the Project
<p> There are quite a few items needed to get this project going, for instance, in order to get accurate time and data logs another item would be easiest integrate into the system. Adafruit DS3231 is designed to keep track of RTC data using a battery so in case of power outage, it won't reset. If we integrate through pi pico alone, everytime the pico resets the log would reset to jan 1, 2021 12:01 etc.. </p>

<p> So here we are, along with contactors, step ups, and few other miscaleneous stuff to get high voltage things going, here is the list. </p>
_I have worked around the above by coding an update on startup. Not really sure that part is needed anymore, but now that I think about it, would be nice to have a battery. Sometimes the pi doesn't update the time correctly on startup could be an issue._

Components Needed:
- [x] [Adafruit DS3231 (Precision RTC Breakout)](https://www.adafruit.com/product/3013)
- [x] [3vdc input 24-380vac output relay](https://amzn.to/41h5ESE) [Picked up 4] *These would not work right, 3.3v even tho they are rated for it, wouldn't cut it on. Possibly not enough amps through pico alone.
- [x] 8x opto coupler 3.3v and 10a 125vac rated switching leg. NO/NC *This is what I'm using to cut AC, Heat, lights, humidifier, dehumidifer, and possibly other stuff.
- [x] 8x opto-coupler 3.3v input and 10a 125vac rated switching leg. NO/NC
- [x] 2x Temp Probe
- [x] 1x Humidity Probe
- [ ] 1x Humidity Probe (Haven't coded this in yet now that I think about it)

<p> It seems there are 8 channel relay modules on amazon with a pinout for elegoo pi boards. Would be good for staging fans and/or lights. Although the lights can take 12 amps per 2 led boards I have. So would be more preferred to go with low voltage coil relay with high voltage output. Trying to think what else it could be useful for. Small switches and open/close sides on 8 channels.</p>
I pretty much have everything I need now. I'll edit this later. Just didn't like having it in the repo.
