wireless transmission using RF module interfaced to ATMEGA 8

Started by maheshnmys February 11, 2011
We need to transmit digital data over a short range( 30 feet ) at a data rate of 8K bits/sec . please suggest me a RF module satisfying these conditions and also can be interfaced to ATMEGA 8 easily

There are a lot of RF modules that can do that. A Zigbee module should be
fine.

Bluetooth?

Hello

You may use the Ezurio BTM-402 Bluetooth module.
The interconnection with Atmel microcontroller is by RS-232 serial port and support AT commands.

Check newark.com or mouser.com

Yes, there are dozens of choices out there. No point in doing the O.P.'s
homework when the answers are only a Google away.

For only 30 feet in a laboratory, consider flashing an IR LED. You will
learn a lot if you do it right. If you do it wrong you will also learn a
lot.

Hopefully Edgard isn't seriously recommending an RS-232 interface? Gross
overkill.

Bluetooth is also gross overkill, but throwing prebuilt modules together
might get one through the class assignment.

ZigBee is a good option. Many complete kits with internal AVR that one
might run one's application on the same CPU as managing the RF.

TinyOS is a free and smaller near-ZigBee. Supported by many vendors and
CPUs including AVR. http://www.tinyos.net/ "TinyOS is an open source,
BSD-licensed operating system designed for low-power wireless devices,
such as those used in sensor networks, ubiquitious computing, personal
area networks, smart buildings, and smart meters."
