simplest RF transmitter

Post by Henke »

I want to build a very simple RF transmitter. I only want to detect the presence of the signal or not, so no information needs to be transmitted (a simple is there a signal or not is enough). The range should be up to 10m and it needs to be very low-power (batteri driven 3-5 V). I also want to use as few components as possible (device needs to be very small).

-Any ideas where i can find the proper information, or even better anyone knows of a of-the-shelf device that i can use or knows of a suitable schematic?

Thanks a lot/

Henke
