The product allows the detection threshold overrun (upper and lower) for each sensor according to the following diagram:

YES

tion
All the beginning of the process follows the same principle as in periodic transmission except that the reference period is the acquisition period
instead of the transmission period.
The product sends a frame of data at the threshold overrun and also during a return to normal.
