The 8-bit event for the liquid sensor contains a relative measurement of the resistance
between the probes with a scale of 0-255. Different liquids will have a different resistance
through the material (water vs fuel for example), so this measurement can be used to set the
threshold properly as defined by the configuration message in the Downlink section
