I would like to create a small compact PIR sensor, that when triggered would set off a short alarm sound in another room of the house. Also possibly make a light begin to flicker or a few seconds. How would I go about doing this? I found the PIR sensor I would like but I do not know how to get the signal from the top of the stairs where the sensor will be to either the living room or my bedroom downstairs. If you need more information just ask me and any help would be greatly appreciated. Thanks
