arduino nano in a humidor

Projects General Guidance
1

I am planning to use the Arduino DHT-22 in a humidor for my cigars. I was wondering if there would be a humidity problem with putting my Arduino and lcd in the humidor, or would a 65-70% humidity level be a problem with the Arduino? I can put the Arduino outside of the humidor, but it would be a cleaner look if it was on the inside. (I plan on cutting a rectangle to show the lcd on the outside of the box)

Thanks

I live in Houston, Texas and it’s a rare day we have less than 70% humidity outside...

Now a real issue about putting that inside the box would be the additional heat your introducing as well as the “smell” of circuit boards and if a component fails and frys, definately might contaminate your collection. I do t speak cigaresse, but seems adding a new description “ has a note of zener” does not flow well.

Maybe put the circuit outside, and only the sensor inside.

Can you give the nano its own compartment in the humidor? In the base perhaps and just run wires to the sensor & lcd?
