bits = rdrhandle:sensors()SYNOPSIS
DESCRIPTION
Returns the last polled state of the reader's sensors. The return value is a bit-field value. Meaning of bits depends on the specific reader hardware. For normal use, it is usually not necessary to make use of these status bits. In fact, using these status bits will break upgrade compatibility as more different reader types are added to the v4kf library.
Following is a table with bit definitions for the original Leadus V4KF. Note that other reader models will put different meanings on the sensor bits.
