    Looking for a low cost implementation to post ambient temperature readings from a sensor to servers via a COTS router.

    1) Have a temperature sensor connected to a micro controller which sends data via a Wifi Module with a TCP/IP Stack to servers 2) Have a temperature sensor communicated via Zigbee to a coordinator that is plugged into a router and communicates with the servers.

    Would like to keep the cost of the solution below $20. Another constraint is the battery life. Wifi modules with TCP/IP consume more power and cost more.

    What particular devices/chips/microcontrollers would you recommend to solve my data communication problem and fit within my budget?And I found some at http://www.kynix.com/Product/Cate/123.html ,are they suitable?
