I'm looking for the smallest embedded device I can find that can do: 1. Infrared sensor 2. Wireless connection (can connect to an G router, for example, I'll have to check the distance that might cover, otherwise maybe N will have to be used) 3. DHCP 4. Low power consumption 5. User solar power to save battery life? At least have a couple out of 5, and I can try to work on the others. I'll need the infrared sensor (beam break detector) to trigger either a single UDP packet or TCP (handshake) and all. A tall order? ;-) How can I get started? Any ideas? I need perhaps wireless connectivity up to like 100 feet to start, and might also need a strong enough signal to go through a few solid walls... Bluetooth is out...

If you use a different wireless solution and have a receiver box that does the IP networking for you, it will be a lot easier to get the power requirement way down. Wireless security sensors run for years on battery - sometimes even longer than the shelf life of the battery, and range is much better than 802.11x. You could use an OTS transmitter/receiver (check Honeywell, GE, Visonic, or even X-10) and hook it in to whatever networking solution you want... If there is more than one wireless beam per site, I bet it would also make it more cost efficient this way. </A>

Can you tell me more about "OTS"? I can't seem to get on the right track with either google.com or deja.com... Marco
