Transmitter Compatible With PIC

[EN0]

Hey Everyone,

I'm working on a project that involves extremely low power consumption. In the design, I am using a PIC to activate a transmitter (powered via a solar panel and rechargeable battery) that will then send a data code to a receiver and to another PIC. This in turn, will display the message I want on a LCD. I was wondering what people have done in the past to achieve something like this and especially what transmitter you used? The maximum distance would probably be 75', and it has to go through a wall. I know there are several FM transmitters out there, and they have been suggested to me, but they use voice modulation instead of data. So, I'm unsure of how to go about this with a PIC.

Any help would be appreciated!

Thanks,

Austin

Use a licence free radio module, correct part for the job, and legal to use.

"extremely low power consumption" and "The maximum distance would probably be 75', and it has to go through a wall" are mutually exclusive, unless the TX can have a very low duty cycle.

These: SparkFun Electronics - RFM12B-S2 Wireless Transceiver

If you search, you can find some power info with a AVR here:

Thanks for all the advice and suggestions everyone!

Yes, I suppose I exaggerated that "extremely low power" statement, it doesn't have to be that extreme, but relatively low power.

Thanks for the links, I'll look into that.

BTW, I'm going to be using the BASIC stamp for my first prototype, then I'll use a PIC.

Thanks,

Austin
