Hello everybody, I have a telescope and I want to shield the parts from high humidity and avoid low temperatures. I have a dehumidifier and a thermal pad and I would like to connect them to sensors that would control when they would be turned on or off. I have very small experience with electronics (some course in college about a decade ago) but I can find my way around a breadboard and I can program (not a developer, a matlab guy, but you get the meaning..) So I was thinking about plugging an arduino to a temperature/humidity sensor and control the two devices with a relay. I am not looking for a ready solution (I am sure I ll find something if I keep searching the forum - just been here for 10 minutes) I just have one or two general questions, the most important one being , Which components and which arduino? Searching the net I find many different choices for arduino and dont get me started on the temperature/humidity sensors. So, to begin with, which arduino do you think would be more appropriate for such a task, taking in mind first that I want to avoid overkill? Secondly, does it really matter which sensor I buy? (Considering ease of use when programming them and accuracy more or less. But ok, I dont need the readings to be 100% accurate.. ) They way I think about the whole setup is this : 1. Arduino 2. Breadboard and cables etc 3. Two relays for switching on and off the devices 4. A temperature/humidity sensor (or different sensors ?) 5. Two knobs for inputing the desired values (one for humidity and one for temperature) - something else would be better perhaps? please advise if possible. 6. perhaps an lcd screen?? Am I in the right path with this? Thanks in advance for any help.
P.S : In case you DO think this, NO I am not a college student,neither a schoolboy looking for easy answers for a project. :D Thanks again Steven - Greece
