Hi all, I'm about to start my first project and would need some advice for what hardware I should get.

The goal of the project is to have a motion-sensor that monitors the movement in a room at a minimum of 90 degrees v/h. When movement is absense for a period of time an IR blaster/tranceiver should turn of the TV in the room.

the device will be powered by the USB port on the TV, apart from that I'd like to keep the unit slim. Soldering is fine if needed.

Thanks
