I'm very new to Arduino and honestly I haven't yet accomplished anything with it yet.
But that doesn't put down my ambitions
I have in mind a project that involves one master Arduino Uno and one or more secondary Arduinos Nano to be used in the car (which typically means noise).
My question is this: If I want to use few sensors e.g. thermal sensors and tilt sensors (like "GY-85 sensor module ITG3200/ITG3205 ADXL345 HMC5883L") does distance between arduino and sensor is a problem?
Of course I understand that more distance - more noise and more wire resistance. But I have no idea of scale of the problem. Can I count that distance 3-4 meters for this sensors is ok? Or not? There are digital and analog sensors, which one should I prefer when taking into account this kind of distances? If these distances are problem then is there a solution to work around the problem?
And secondary question if I may: If I want to use few thermal sensors, is there a existing easy way to calibrate those? And more importantly to store that calibration data into arduino software?
Thank you guys!
