I want to know if there is a timer out there that actually analyzes the humidity level and turns on the fogger when it drops to a certain percentage?


Reason being, right now I'm using a normal timer from the pet store. I calculated how much my humidity drops within a given amount of time so that I know how I want to set my fog timer. But this is not a good method, because at the initial stage where I do my calculation, that calculation is based off the current humidity level of the outside world. So basically if the humidity were to drop here, the humidity level inside the frog tank will naturally fall faster than my initial calculation. So basically it makes the timer semi-useless.

Does anyone know of a product that turns on the timer only when necessary? I want to be able to tell it to activate only when the humidity falls under 80%.

any ideas?
