PEACE OF MIND

This project turned out well for my first wireless design and my first attempt at using a Freescale HC08 microcontroller. The combination of the MC9S08GT60 microcontroller, the MC13192 RF transceiver, and the Simple MAC software enabled me to rapidly develop a complex wireless system capable of monitoring several useful remote sensors. I built the system quickly without the worries of complicated RF design issues. As a result, I was able to focus on developing the rest of the system.

Now you can build your own system. Hopefully, it will give you some peace of mind when you’re away from your house. Just think: now you can check for problems anytime you want.
