Battery powered PIR and temp/humid sensor

@Mark-Swift I used a ProMini 3.3v. Unfortunately, I have no schematic. Since I used breakout boards anyway this is not a big deal. You connect those boards to your power, ground and a digital pin or on SCA, SCL pins. I don't know what the power consumption of the Nano's is. So that is something you have to try out.
