Arduino driven humidor with web logging

Humidor is a device that tries to keep humidity and temperature at desired level. Normally they are stand alone devices that can be refilled with water to keep humidity at level. Dzzie decided to add DHT22 humidity and temperature sensor to it and along with Arduino log this data to webserver.

He wrote a PHP script that records humidity and temperature data to database every 20 minutes. There is also a trigger mechanism which sends an email alert once one of parameters gets out of safe range. Humidor sensor is run with Arduino with LCD shield. It has a feature to record time when water is refilled. If you use humidor in sensitive area – then accessing data online might help a lot.
