Need coding help.

Former Member

So I have never coded anything before in my life and I found this community from the jeremy blum youtube videos.

 

I am building a vivarium (snake cage) and would like to fully automate the temperature and humidity for it and be able to monitor and adjust the temp and humidity wirelessly over my home network. I have done a lot of research on my own and think I have all of the right parts I just need help with the coding and one small wiring connection. I will list as many details as possible below and I would love if someone here would be able to help and teach me!

 

PARTS LIST: Arduino uno r3, AM2302 (wired DHT22) temperature-humidity sensor, adafruit cc3000 WiFi shield with onboard ceramic antenna, Sain smart 4 channel solid state relay (load: 2A, 240VAC, 50/60Hz), Humidifier runs on 30 watts 120V, Ceramic heat lamp 100 watts, shield stacking headers for arduino r3, breadboard, wires, and resistors.

 

What I would like is the sensor to be in the cage (hence the AM2302 not just the DHT22) and the rest of the components outside. I would have the parameters set (Ex: 83 *F and 85% RH) and any time the actual temperature or humidity fell below those values the ceramic heat lamp and/or humidifier would turn on until those values have been reached and then they would turn off. Finally (and not a fully necessary requirement) have the data wirelessly sent to my computer over my home network so I can see actual temperature and humidity at that time and change it if so desired and a graph of temperature/humidity over time. This part is not needed I just would like it if it is possible to do.

 

As stated I have no experience in coding but I am handy with electronics and quick to learn. I do not know how difficult something like this is I just know it is way over my head.

 

If there is any information missing or any questions feel free to ask!!

 

Thank you in advance!

    Its not dat hard boy  but i probably would go some other Method coz if it fails somehow i could harm or kill your snakes. i would stick to normal controles. since once a friend did something simular but somehow it did broke and all his plants did die in the automated growbox. just be very carefull with such automated mechanism for living beings.

    Nobody wants to see any snakes harmed here.

     

    One device that, in concept, could help here is called a thermal cutoff.  It acts like a fuse, but for ambient temperature rather than current.  Unfortunately, your snakes would be parboiled before it actuated.  You could design a thermal crowbar (or alarm) that would work.  You could limit your load power so that in the 100% duty-cycle condition things only get a little warmer than desired.  Snakes AFIK, can see in the IR.  If you provide an un-heated part of their enclosure, maybe they would have the wit to slither over to it if things got too toasty.

    I have found there is nothing better than having a good book or two to refer to. I recommend Arduino Cookbook by Michael Margolis, Beginning Arduino Programming by Brian Evans and maybe there is something related to what you are doing in Environmental Monitoring with Arduino by Emily Gertz.

    These can be purchased from Amazon. And of course as always Youtube has many tutorials but I found having a book makes learning much easier and you have the reference right there.

    Just a thought.. Locate the temp and humidity probes away from heater so that you do not have a turn on and cool down affect. Maybe look at a range of valid temps with the high sounding a warning buzzer to save the poor devils.

    You may try instructables.com. If you can't find exactly what you are looking for. I'll bet you find something close.

    Thank you to everyone for your posts. I have been very busy with life lately and was able to read your replies but not respond to them.

     

    First of all I agree paying is not the way to go that was a fault in judgment on my part haha.

    Second of all I have spent a great deal of time learning coding and what not from online sources when I have a chance and have wired and coded things to work how I wanted with out the wifi part!

     

    So it is all set up and working how I want but I am starting to think the wifi shield i bought is faulty. No matter what I do I can not get it to talk to the arduino even when using pre made code for that specific shield. I will keep this updated as I can!
