I have a large bedroom and want to take the temperature in all 4 corners plus close to where I normally sit by my PC. My basic idea is to have 5 sensors connected to the Pi which saves the sensor data in a database which I can generate graphs from over time. To start I'd be happy to view current temps via SHH into the Pi and then take it from there. So I've a few questions:
Considering the size of my room the cables going to the sensors would need to be quite long as I'm going to trace them along the walls, will that have an effect on the accuracy of the sensors?
Is this possible from a single breadboard?
