I have an automatic misting project for a vivarium that I've been working towards, and I'd like some input on the wiring diagram I have for the project. I have the Pi's GPIO pins hooked up to a breadboard via a ribbon cable. There is a temp/humidity sensor hooked up to the board and a power switch relay hooked up to the board. I plan on reading the humidity from the sensor and subsequently turning the mister on if the humidity is below a certain threshold.
I made this diagram based on some preliminary internet searches about examples, code from similar projects, and the sensor and device documentation. At this point though I don't have enough experience to even ask a specific enough question about the wiring diagram I have. Therefor I am looking for some general feedback about its functionality, improper configuration, etc.
Thank you for any input you can provide,
