Hi,

I need to take data from a sensor and transmit it to the processing unit. I intend to use a wireless transceiver at both ends. The baud rate is 250-500 kbaud. The output signal from the sensor comes between -18 to 24V (extreme cases in either direction i.e. clockwise and counter clockwise) and the current is 130mA.

I came across CC1101 transceiver by TI. How effectively will it solve my problem? Are there any other options possible that I must explore?

Thanks

You have to provide more details on what wireless communication standard you are going to use. CC1101 is a sub 1GHz RF transceiver. There are others who also have similar ICs.
Are you looking to build the RF module yourself using these ICs or you want a ready module? If you would like to build your own module then CC1101 will be good, also check in Atmel, they too have good ICs.
If you want to use a ready module, then I suggest Digi International's products. They are easy to work with.

Hi ravindragudi,

I was looking at ETSI EN 300-220 standard for short range devices. And that's how I end up with CC1101 transceiver. But now I'd rather go with Digi International's Xbee module.

If I go with Xbee module will I be able to program it to high baud-rate so that I do not lose any data from the sensor? Also I am worried about sensor output current. I guess it would damage the module beyond repair.
