Relaying data between Arduino and Android devices

Although polling for and displaying data from an Arduino using a web browser isn't anything new, those who are looking for a more user-friendly method of interface may find the following interesting. Arduino forum member "bradipao" has demonstrated how to gather data from a DHT22 temperature and humidity sensor and make it available to connected devices via an Ethernet-enabled Arduino board.

However the new part is the code for an Android app that can retrieve and display the data from the sensor. As well as data display the app can also poll the subnetwork for the IP address assigned to the Arduino board as well. The system is demonstrated in the following video:

For more discussion, information and links to all the required code, login to the Arduino forum. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

If you're looking for a sensor to measure temperature and humidity - check out our HUMID: humidity and temperature sensor module. Designed around the DHT22 sensor, it only requires one digital pin and power - and is easy to use with out Quick Start guide. With a temperature range of -4°C to +125°C with +/-0.5°C accuracy, and humidity at 0-100% with 2-5% accuracy you're ready to measure. For more information and to order, click here
