Hello,
Does anyone know, for an advanced amateur, the cheapest (but quality of course) evaluation kit for very low cost RF Transceivers. I plan to "sensor" my house so I need to base station and least 20 "remote" stations.
Thanks in advance for any responses,
Larry

** Kinda, slightly interesting to know if your " sensors " are simple on/of switches or maybe hi-res colour video cameras.Might affect whether you idea is doable or insane.

What kind of data will you be sending over the air - a few bits, serial data stream, video, etc.? What is your definition of very low cost? There was a guy a few weeks ago on comp.robotics.misc who wanted to control a stepper motor with low cost. When someone suggested a $15 stepper motor controller, he said thanks but it was too expensive for him. Oh, brother!

Hi Guys,
Thanx. I will be sensing just voltages so I will be transmitting/receiving one to no more than 15 bits. I hope to keep the average cost per station below $25 and the cost of the whole mess below $600.
Thanks again! Larry
stations.
Given that you could do it with a $2 microcontroller and some discretes I can see his point.

I am also doing something similar and I don't want to deal with discretes, so I ended up opting for Maxstream Xbee modules. They are cheap ($19) and they are high quality. They work on the Zigbee standard and mesh networking is possible.
