Looking for a water pump for a project, but im not sure if what I need exists?

I am trying to find a water pump to create a drip/sprinkler style itrigation system based on relative humidity inside a reptile enclosure. I have a humidistat that reads the humidity and will kick on the system at specific times, if humidity falls below a specific threshold, or at specific times if humidity is below a specific threshold. It works through voltage regulation, so I'd have to plug the pump into it, and when humidity falls to a certain point, it will then supply power. Once it reaches a certain maximum, it will kill power. The issue is, because it will take some time for the water pumped in to evaporate with the heater installed in the enclosure, I need it to have an "auto off" timer. Most reptile mister/fogger systems I have seen either require a set time that they come on or require a button press to turn them on, so just supplying power won't start the process. What I am ideally looking for is a transfer pump (or a submersible, either could be made to work) that will self cycle on for two minutes, off for 10 minutes, on for two minutes (or a similar time frame-being able to set a custom time would be ideal, but preset would be fine as long as it's close-ish) to allow time for the water to start evaporating and reflect on the humidistat. This function would need to persist even if power is shut off (by the humidistat ) and start automatically when power is supplied. Basically I'm trying to build a lawn sprinkler system, but rather than "come on at 8pm, run for 20 minutes" I'm trying to get it to "come on at %RH, run for 2 minutes". A friend suggested a raspberry pi or other arduino controller for this, but I dont have the foggiest idea how to set that up, and the hunidistat was already reasonably expensive, plus the cost of other materials, id rather not spend another $150 on top for the equipment to do an Arduino if another option exists. Thanks for any tips or advice! submitted by /u/PyssDribbletts [link] [comments]
