3G shield

　An Arduino is a small computer which you can use in anyway. A 3G shield is an open source hardware, an expansion board which has 3G communication facility (the facility makes Arduino use the internet and portable communications on it).
This facility can connect with an Arduino. IEM module (made by AnyDATA) used as the 3G communication module. By using an Arduino, we can develop M2M by construction of 3G communication network and make a remote control robot.

Comfortable Manager

The thermometer and hygrometer which is put in your room calculate the discomfort index. You can know it on your smart phone from outside, and you can control the air conditioner.

☆System

　 First, the thermometer and hygrometer calculate the discomfort index. If it reaches the regulation value, an email is sent to your phone. You put Arduino, 3G shield and TAB shield whenever you want in your house.
For example, the temperature and humidity increased and the discomfort index would be more than 80, the 3G shield send you an email. The temperature, humidity, discomfort index, and the Webf form URL to operate your air conditioner are written on this email.
I made this program not to send emails again when the discomfort index is over the regulation value for long time. If it gets down once and become over the value again, an email is sent again. I gave this program ten seconds to wait. Because of this, this program does not send you emails again and again if the discomfort index fluctuates around the regulation value, and works really stable.
