SENSZY V.1

I’m sick and tired of pressing buttons to turn on lights and fan of my room, so I thought of making an automation circuit for my room, but I wanted no buttons to press even no screen to tap, no android interface, no IR remote, I wanted it to be completely autonomous system. So, I came up with this circuit which makes use of two PIR sensors and a ATTiny85. I wanted to use as minimum as possible hardware.”
