Libelium has launched a survey to ask developers and companies which sensors they would find useful a mote to bring. They are currently working on the development of the sensor integration board for Waspmote and they want to take into account your opinion. Think in a WSN project you would like to develop and tell them which sensors the motes should have to bring. There will be a prize draw for a Waspmote Developer Kit among all the participants.
