Hello
how can i connect a seismic sensor ( with 6 pins ( 3x(+/-)) to an arduino mega and read data for it?
I'd start with the sensor's datasheet to see how it works
kurapika89:
Here is the manual:
And what does it tell you?
3axies with 6 pins 5volts
ground pin, test pin ...
2pins for 12v power
am i missing something?
am i missing something?
Yes.
- What is the expected signal output?
- Can this be measured by an Arduino?

Yes.

The output signals are differential. One pin (+) provide a 400 V/m/s (500 V/m/s) output signal and the pin (-) provide also a 400 V/m/s (500 V/m/s) signal :
Can this be measured by an Arduino? I'd really want to know.

Not accurately. The Arduino measures voltage in 1024 steps. For a 5V reference, the levels are about 5 mV per step.

so is it a blocked end to make an acquisition system for this device? or we can find a workaround ?
What voltage range, at what voltage resolution do you want to measure?
How many data points per second?

The 400uvolt is important for me .. i dont know how much i can get as a max volt.. but small vibrations are important.
I want to have as much data as possible .. i need to analyse the smallest information i can get.
Thank you
The the Arduino is not for you.

Can you tell me whats the best performance i can have from arduino?
If arduino is not for me .. whats the workaround?
Thank you.
Use a laptop or other computer with an appropriate interface.
