Planet Arduino

The Dht22 sensor is installed in the humidor.

The arduino takes a reading every 20 minutes, and uploads the data to your webserver.

The PHP script will record the data to the database. If the temp or humidity is out of desired range, it will send you an email alert.

Alerts must be manually cleared latter by logging into the web site, so you are not spammed, before you get a chance to fix it.

When you add water, push the select button on the LCD sheild to record it. This will be saved to the db as well. Power resets will also be recorded to the database.

See screen shot for example web report.

Temperature controlled humidor with web logging, monitoring and alerts - [Link]

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.
