Checking straw bale wall moisture levels & all things monitoring

I have the opportunity to add “smart” technology to my house as I’m building. I’m considering using either, or both, arduino boards & Raspberry Pi computers as the main processors to which I’ll attach various sensors and switches.

Primary considerations will be power consumption, heat production & cooling, and reliability. Both Arduino and Raspberry Pi units use very little power, especially when compared to their utility. I’m not sure about how much heat they produce however, hopefully, I’ll be able to position them within the house in a place where they can be easily and consistently cooled. Maybe the heat can be re-used somehow?

Moisture sensors are an obvious requirement – dampness & water being the worst problems for straw bale walls.

If we have the budget I’ll add controls for automation of lights and other electrical appliances that we can run to a central control
