SensorConnect has to be used our 200 series products, found here. There are many how-to videos to help user's get up and running, found here.

The 200 series wireless nodes have 16 Mbytes of datalogging memory.  

Now the question arises, ‘how long can a node datalog before its memory is full?’. The answer is that it varies depending on how many channels are being sampled, sample rate, and data type. Here are two examples:

V-Link-200 set so that channel 1 is enabled with a sample rate 2048 Hz, and data type of Float(4 byte).  Our calculation would be:

  • 1 channel x 2,048 samples per second = 2,048 data points per second
  • 2.048 data points x 4 byte float data packet = 8,192 bytes per second
  • 16 MB (rounded down) ÷ 8,192 bytes per second = 1953 seconds (rounded down)
  • 1953 seconds ÷ 60 seconds per minute = ~32 minutes to fill the memory

G-Link-200 set so that channels 1, 2 and 3 are enabled with a sample rate of 32 Hz, and data type of int24(3 byte).  Our calculation would be:

  • 3 channels x 32 samples per second = 96 data points per second
  • 96 data points x 3 byte int24 data packet = 288 bytes per second
  • 16 MB (rounded down) ÷ 288 bytes per second = 55,555 seconds (rounded down)
  • 55,555 seconds ÷ 60 seconds per minute = ~925 minutes (~15 hours) to fill the memory
