I did consider this but i was looking at the boxford covered up in the garden pooring with rain and decided i wanted to do something and i just decided i had a 5 relay board and small 12v powersupply so i did it, it may be overkill but at least with the relay design i can utilise the sensors output without a PC fullfilling my manual control Obsession!!! lol
