A popular contemporary project is to take advantage of the various sensors on the market and thus report on environmental conditions either locally or remotely with an Arduino. One example of this has been published by Instructables user "donmatito" who shows how to connect a wide array of sensors including temperature, humidity, noise level and more - and then send the data to the Thingspeak online service which allows collation and remote display of the resulting sensor data.
It's a handy tool and a good way to demonstrate remote sensor access. For more details visit the Instructable. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
When connecting a multitude of sensors and using large amounts of memory for your sketch, or you're stacking on Ethernet and microSD shields, or all at once - it's time to upgrade to the Freetronics EtherMega:
Quite simple the EtherMega is the fully-loaded Arduino-compatible board on the market today. Apart from being completely Arduino Mega2560-compatible, it includes full Ethernet interface, a microSD card socket, full USB interface, optional Power-over-Ethernet support and still has a circuit prototyping area with extra I2C interface pins. So if your project is breaking the limits, upgrade to the EtherMega today.
