Arduino wireless Sensor Network programing

We are looking for a long term relationship in order to develop diferent kinds of products about Wireless Sensor Networks (WSN) First of all, we are going to develop some prototipes with arduino and shields. Then we need to develop the PCB and the whole product (Not included in this deal) In this firs steep, we are interested in a simple software for an Arduino device. We will use comercial products from [login to view URL] (We can provide the hardware for testing purpouses) The hardware will be: 1.- Seeeduino Stalker - Waterproof Solar Kit ([login to view URL]) For more information see the Wiki ([login to view URL]) 2.- GPRS Shield ([login to view URL]) For more information see the Wiki ([login to view URL]) 3.- Some Tº Sensor 4.- Humidity sensor This device, will read and send the following parameters: 1.- Tº Sensor. 2.- Humidity sensor. 3.- Battery status. And then the GPRS Shield it will send the data to a pachube acount ([login to view URL]). See the pachube example code here ([login to view URL]) It is important the energy managemant because it is solar powered. We can provide more information. Thanks for your time.
