Components (continued from Mushrooms' Paradise #9. PI components review in detail. Part 1 )
3v Relays
There were not a lot of 3v relays options. I got mine here and they don’t have any specifications listed.
But it looks like they need less than 16mA, otherwise they will not work.
IoT Relay
It is used to run a humidifier. The description of the IOT relay can be found here: IoT Relay
Signal is 3.3v coming from PRI pin 16. I really like this relay and definitely will use it in the projects which require 110V.

Other
I didn’t solder anything, all the components are connected to the breadboard using jumpers and solid wire. I plan to expand and add more components in the future.
To attach lights and fans to the enclosure I planned to use nano tape. It holds lights alright, but doesn’t hold fans. For now I just put fans on the shelves, until I find a better solution.
The final result
Demo run
I modified time intervals for components to show the demo run of the farm.

I will put mushrooms’ cakes in the enclosure hopefully today.
