I’m using the Arduino Uno with the MPU6050 (Sparkfun board*)Inertial Measurement Unit, using i2c protocol. I’m trying to position the sensor with a battery, in a probe about 4 meters far from the Arduino Uno. I need three signals Clock, Data and Interrupt.
With normal jumpers, I haven’t any communication problems , but if I try with long wires I have many problems .
With three separates coaxial cables RG174/U, Øest 2,79mm, 101pF/m, 50Ω, 34 AWG, I have some signal and I can read the raw data.
With a three-pole coaxial cable Øest 4,52mm, 30 pF/m, 53,477692 Ω/km, 22 AWG i cannot even initialize the sensor :~. (I don’t know if I can attach the datasheets of the cables)
I am not an electronics expert and I have some problem in choosing the right type of cables. I read that it is important to have a circuit with a low capacity so i chose the cables with less pF/m. Does anyone have any suggestion? is it possible to do such a thing ? or should I use other hardware to amplify the signal?
thanks to everyone for the help!
