If you’re a cigar aficionado, you know storing cigars at the proper temperature and humidity is something you just need to do. Centuries of design have gone into the simple humidor, and now, I guess, it’s time to put some electronics alongside your cigars.
The design of [dzzie]’s smart humidor consists of an Arduino, WiFi shield, LCD + button shield, and most importantly, a DHT22 temperature and humidity sensor. In a bit of thoughtfulness, only the DHT22 is mounted inside the humidor; everything else is in an enclosure mounted outside the humidor, including a few buttons for clearing alerts and logging when water is added.
The smart humidor reads the DHT22 sensor every 20 minutes and uploads the data to a web server where useful graphs are rendered. The control box will send out an alert email to [dzzie] if the temperature or humidity is out of the desired range.
Smoke weed everyday!
This is for storing and aging fine cigars. Weed does not need controlled humidity or temperature.
You poor, unfortunate, ignorant man.
Weed should be kept at an RH of 65%
Yes, I have a question for Dr. Dre. Is it ok to smoke a cigar alongside the weed everyday? Wha what what?
Why the hell did I read the title of this post as “The Brain Humor”? WTF is wrong with me?
Smoking can kill you!
So can living.
Yeah, but no one likes a quitter.
I have a problem with those temp + humidity sensors. A friend bought a few(5ish maybe) and tested in the same conditions there was almost 20% RH spread and over 2 degrees C temperature spread. They were purchased from ebay…

I am aware of that, but that experiment happened on the breadboard, prior to any soldering.
A friend and I did something similar for a mushroom terrarium. We used an Arduino UNO, DHT22 (the DHT11 only reads up to 80% humidity), shift registers, x2 7seg LEDs, x2 relays, a Sparkfun heat pad and a humidifier.
We cracked open the humidifier and ran one of the 5v lines to a relay, also hooked up the heating pad to a relay and a separate 9v power source and voila – an automated terrarium. The UNO would constantly read the humidity and temp, turn on the heating pad if temperature dropped to a certain level, and turn on the humidifier if the humidity dropped. Obviously the 7segs are to display the temp/humidity.
It turned out great, and the DHT22 gives us perfect readings (we’ve compared it to an analog hygrometer and thermometer.)
We bought the DHT22 off Amazon – Mike’s link to Sparkfun is also worth the read since re-hydration is an issue.
So would the next step up be something like the Sensirion SHT15 or Honeywell HIH6130 with their claims of better than +/- 4% RH accuracy?
The Honeywell is interesting in that it is a $30 part with I2C and built-in alarm signal line features,
Electronic cigar humidors. I want to own one. Hope it will be not that much expensive.
What about this?
