Radio ICs cost over $2 and MCU's are currently in the $4+ range for ones that can support 802.15.4 and/or TinyOS. The $1 price tag requires volumes that we aren't even close to achieving. The cost you pay for motes include the price of the components, the cost of designing and manufacturing the board (remember that someone has to be paid to put the components ON the board), and the cost of doing business. > But, the xbow.com MOTE prices are less then anywhere else and with > more sensors and sensor network products.

For a particular application, the cost will be lower by optimizing the hardware specifically for that application, but what Xbow sells is a development system with pluggable sensor boards and interfaces. The development and general nature adds cost to the device (a 51-pin connector costs over $2 from digikey!). -Joe On Thu, 03 Feb 2005 15:26:46 +0100, Dominique Blas <[EMAIL PROTECTED]> wrote: > Tsenka Stoyanova a �crit : > > > Hi, > > > > Interesting question.
