median
Computes a median value from many samples¶
A Sat/XLink setup is associated with this module: median_setup.txt
The setup requires that one measurement be setup to collect samples from the sensor (e.g. every 5 seconds). It gets connected to the one_sample script function. It does not get logged. Instead, the samples get stored in temporary memory. A second measurement is setup to compute the median. It is a manual entry measurement (it does not sample the sensor). It should happen less frequently than the first measurement (e.g. every hour). It is logged and may be transmitted.
