Libelium's new Wifi module for the Waspmote platform enables sensor nodes to send gathered data to Web servers in the Cloud and to any Smartphone device without the need for a special gateway, easing the deployment of sensor networks. The new radio module adds an extra layer of intelligence to the nodes, allowing them to send collected data to any web server in the Cloud. The Wifi sensor nodes will also send data to any iPhone or Android device nearby by creating direct links with them.
The Wifi radio extends the possibilities of The Internet of Things to iPhone/Android apps developers, allowing direct communications between the sensors and the smartphones without an intermediate router. Sensor nodes can connect directly to Cloud servers using a standard protocol such as HTTP.
The new Wifi sensors are also capable of using the secure version of the standard web protocol HTTPS, ensuring the privacy of the information sent, a major concern when deploying wireless sensor networks in cities. They can also create TCP and UDP connections, enabling developers to design their own communication framework between the sensor nodes and the Cloud servers.
Libelium provides an intuitive and open source programming API and complete documentation with examples to help developers to easily start working with the platform. Demo applications for iPhone and Android are available for free, in order to easily test the new Wifi sensor capabilities from any Smartphone.
