WSN node sampling and conditioning

[vnprado]

We are looking into the possibility of using the NI WSN-3202 for our new data acquisition system. What is meant by minimum sample interval? Lets say we use an accelerometer for the node. Will it be able to transit all the data acquired over that amount of time? Or does it only read the analog signal every second and then transmits that reading?

Also, does the node provide signal conditioning? Like again for example the reading of signal off of an accelerometer, can it be programmed to filter the signal?

We are trying to figure out if we can use the WSN-3202 for strain gages and accelerometers. Also, how is power consumption taken into consideration?

What are the advantages of the NI WSN-3214 vs the NI WSN-3202?

Thank you for any information!

Thank you for your posting. 

The wireless sensor nodes are designed to make a single point reading every few seconds or so.  Consider the following developer zone documents for review.  http://zone.ni.com/devzone/cda/tut/p/id/9365

The temperature node, and the new strain node, do provide signal conditioning for their respective sensor inputs.  However, for vibration and higher speed measurements, you may want to consider a low cost compactRIO system as described in the attached PDF.  THere are a number of radios available that make a CompactRIO system wireless. 

Let us know what questions you have.
