Wifi module for sensor platform
Libelium has a launched a Wifi module for the Waspmote sensor platform. The radio module adds an extra layer of intelligence to the nodes allowing them to send the collected data to any web server in the Cloud. The Wifi sensor nodes will also be capable of sending data to any iPhone or Android device nearby by creating direct links with them.
This Wifi radio extends the possibilities of The Internet of Things to iPhone/Android apps developers as it completes the current connectivity possibilities, which is already covered by ZigBee, Bluetooth and 3G/GPRS, allowing for the first time direct communications between the sensors and the smartphones even without an intermediate router.
These Wifi sensors are also capable of using the secure version of the standard HTTPS web protocol, ensuring the privacy of the information sent, which is 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.
